What is an Electron Shell?

What is an Electron Shell?The electron shell definition is the term used to describe a microscopic particle of matter that forms when electrons and protons go through a series of positive and negative electric charges. In a sense, it can be defined as the central nervous system of the molecule of matter. It is a key feature of the chemical bond that serves as a conducting medium.The electron shell is also known as the so-called electron pair. In chemical bonding, the electron pair plays an important role. The electron shell has a central electron and protons are both necessary for binding the molecule together and in a process called ionization, the bonds between them form a solid.A ring formed from two electron orbits surrounds the nucleus nuclei of matter. The nucleus is made up of hydrogen atoms and the electron pairs, proton and electron, are arranged around this nucleus. This creates a core. The electron shell in the nucleus is actually made up of two electrons.Mass is the abili ty to hold a quantity of something together. The more mass that an atom has, the heavier it is and the more stable it is, as it can withstand a lot of force and heat.The molecular structure of molecules is determined by its number of bonds, length and atomic weight. An atom is made up of three basic elements, namely, hydrogen, oxygen and nitrogen.Hydrogen is used in energy and propulsion. Oxygen is used in air-breathing mammals and plants. Hydrogen gas, however, is a very strong and powerful element. Oxygen is not really used as an element because it can easily decay with other atoms.The energy in the body is held in the cell. When the energy in the cell is released, the body will receive heat. The loss of body energy is known as heat.

My Tutoring Starts with Physics

My Tutoring Starts with Physics There’s little in our universe that the concepts and laws within physics do not explain. We  are the embodiment of physics from the organelles that interpret the language of life in our cells to the cosmic engines that generate heavenly bodies, large and small. Yet how many of us understand how physics work and where they need to go to become enlightened.  After teaching for many years the time has come where my tutoring starts with physics. Though a daunting task, my tutoring may not be of the caliber of Steve Hawking. Yet as a private tutor my teaching skills will rival those of any local university professor. I’ve always wanted to a tutor. The start of my tutoring of physics for some will be to explore the fundamentals of classic physics. The word physics is derived from the Greek word “physis” meaning nature. And indeed that’s exactly what it explains in a myriad of ways. For the discipline of physics crosses all borders of natural sciences. It is the study of matter and its motion through space-time, and the four substances within which all things exist. The four states in which all matter survives is solid, liquid, gas, and plasma. What better way to begin a journey of tutoring then to start with the physics of universal knowledge. Physics is the most direct path to understanding how the universal laws function even and including the murky borders of philosophy â€" it is the physics of philosophy, take into consideration the Tao of Physics. Well into the 18th century physics was still recognized as a discipline of philosophy. Because it straddled for so long the conceptualized definitions of science and matter. The study of physics is still considered to be a priori and a posteriori academic discipline. Priori knowledge is independent of experience. Posteriori knowledge is dependent on physical experience and concepts that have been proven physically correct. So you see how physics can cross and expand into so many avenues of learning. Physics can explains that how what we may observe will not always result in a predicted outcome. In starting my tutoring with physics I will explain in the most basic of terms the dynamics of field theory and how relative space and time can be. Albert Einstein, in a moment of reflection,replaced the notion of absolute time and space. And while not everyone can be an Einstein we can all learn the dynamics of classical physics. No other academic discipline contributes more to explaining life. In tutoring on the subject of physics I will help the student to excel in the comprehension of how the laws of physical dynamics affect how our universe appears.

Cutting Out Sugar The Myths You Need Debunked

Cutting Out Sugar The Myths You Need Debunked pixabay.com In fact, many people actually aren’t aware of how prevalent sugar is not just in candies and other sweet snacks, but in places that you might never have known it existed. For this reason, cutting sugar is a huge lifestyle choice, and one that takes extreme dedication. So, to help you out in your anti-sugar adventures and to eliminate any potential surprises down the road, here are some myths regarding sugar per NBC and the truth that you need to keep in mind. Myth: “You Don’t Have a Sugar Problem” Obviously, this isn’t true. Even if you don’t necessarily have a sweet tooth, this doesn’t mean that you aren’t enjoying loads of sugar on a daily basis. Sure, you’re avoiding the vending machine candy bar, but that’s not to say you aren’t getting the equivalent level of sugar somewhere else. Dietary Guidelines for Americans tells us that our calories intake on a daily basis should include less than 10 percent of sugar. According to blogger Rima Kleiner, we should be limiting ourselves to about 12 teaspoons of sugar a day. Yes, this may seem like a lot, but she claims that “Americans consume nearly twice that much every day.” Anyone eat yogurt in the morning? The amount of added sugars in yogurt is about 6 teaspoons, which means you’re already at half of your daily allotment just by eating a quick breakfast. And you aren’t alone. Apparently, about 75 percent of Americans are overeating when it comes to sugar. Myth: “Sugar is Easy to Spot” I wish. Apparently, sugar is actually hidden in just about everything that you eat on a daily basis. Sugar is often hidden in long lists of ingredients on a lot of the food that you eat. So you aren’t safe if you avoid drinking a sugary drink, because that granola bar in your bag is filled with sugar. According to Kleiner, “there are so many products where added sugars lurk! When people decide to limit added sugars, they know to avoid the obvious offenders, like candy, cookies and baked goods.” However, this is not going to do the trick. According to Kleiner, “Some of the biggest offenders are those that have been given a ‘healthy halo’ like flavored yogurts, granola, energy bars, cereals, flavored applesauce, bread and spreads.” Unfortunately, many products don’t come right out and say there’s added sugars. They’ll instead mention “high fructose corn syrup, cane sugar, corn sweetener, molasses, syrup, fruit juice concentrates and honey,” which are all just as bad. So, as a general rule of thumb, if sugar appears within the top few ingredients, don’t eat it. According to Kleiner, “the higher up these sugars are, the more sugar the product contains.” Myth: “You Should Focus on Avoiding Certain Foods” Nope. (I know, I thought this was true, too). The truth of the matter is taking away from your diet is never going to work. Think about it, if you pack a sandwich, a granola bar and a bag of chips for lunch, and now you have to take away at least one item, you’re going to be hungry faster. The secret is to enhance your diet. According to Kleiner, “the easiest way to keep added sugar intake low is to choose minimally processed whole foods, like vegetables, fruit, whole grains, seafood, beans, nuts and seeds.” So rather than telling yourself to cut out sugar, tell yourself to add more of these foods to your diet. These foods have less sugars, and eventually, you’ll be accidently removing sugar from your diet. Myth: “You Need to Cut Back on Fruit” Have you ever had a friend tell you they don’t eat fruit because of all the sugar? Yeah, not so much. Fruit is actually something you need in your life. According to Kleiner, “yes, it’s true that fruit contains sugar, but that sugar is naturally-occurring fructose.” In other words, this is good sugar. Of course, there are other benefits to fruit, such as Vitamin C, potassium, fiber, antioxidants and other good things you aren’t really getting anywhere else. So this is yet another reason cutting sugar out completely isn’t a great mindset, as fruit may contain sugar, but the healthy nutrients it provides make its consumption a necessity. Myth: “You Have to Say Goodbye to Desserts” Again, quitting sugar cold turkey and never looking back isn’t the answer. Still, rather than binging on a chocolate when you have a sweet tooth, consider healthier alternatives that will give you that same satisfaction. And the best way to do this is to make some homemade treats for your sweet tooth and other cravings. According to Kleiner, “whether you’re looking for bread, canned soup, or yogurt, the best option is to make your own. Make your own break to control how much sugar is added, or flavor your own yogurt by adding” jam or fruit. So to recap, sugar is the enemy, but that doesn’t mean you should cut it out of your life entirely. Just know what you’re looking for, pack your diet with healthier alternatives, and you’re already on the right path!

Housekeeping Tips to Keep Your Home Sparkling

Housekeeping Tips to Keep Your Home Sparkling via Unsplash Create a Routine Cleaning routines are a great way to make sure that your housekeeping is top-notch. Your house will only stay clean if you are consistent with your chores. You would be surprised at how much dust can gather in just a couple of weeks. Designate a day of the week that you will spend time cleaning your apartment. It’s also useful to schedule a certain amount of time that you will spend cleaning. This will help you from getting distracted while cleaning. To stay organized, make a to-do list with the tasks you would like to accomplish. This will help you to stay on track and make sure that everything is done. Deep Cleaning vs. Daily Cleaning There are different levels and methods for housekeeping. It’s important to know the difference between a deep cleaning and a simple cleaning. A simple cleaning should be done once a week and involves straightening up, vacuuming, washing the bathrooms, and dusting. It involves a lot of surface cleaning. A deep cleaning consists of getting into the little crevices in your apartment that you may not think about. This includes dusting your blinds, washing baseboards and windows, and dusting out air vents and ceiling fans. A deep cleaning doesn’t have to happen very often; once a month would be ideal. Stock Up on Cleaning Supplies When it comes to housekeeping, you’ll need some supplies to make sure your home is truly sparkling. You should keep a cabinet or bin stocked with cleaning supplies like dusting spray, bathroom cleaner, glass cleaner, Swiffer pads, and whatever else you think you’ll need. If you want to save some money or are in a pickle when it comes to housekeeping day, there are some cleaning products that you can make with ingredients right from your kitchen. Glass Cleaner For mirrors, windows, and glass surfaces, simply mix vinegar and distilled water in a spray bottle. For a nice scent, add a few drops of essential oil to the mixture. Bathroom Cleaner If you need a quick bathroom cleaner, mix together one cup of vinegar, half a cup of baking soda and hot water and leave in the tub for five minutes. After that, add some more hot water and leave for another five minutes. Drain the tub and rinse. Fuzzy Socks If you’re out of dust rags and you need something quick, grab a pair of fuzzy socks and wipe down the surfaces. Simply throw the socks in the wash and they’ll look like new again. Get Rid of Foul Smells Have you ever walked into your kitchen and wondered what that awful smell was? It’s probably your trash can or the garbage disposal. Many people don’t think of cleaning these items out. If you do start to smell something foul, there are some home remedies to get rid of it. For a garbage disposal, simply throw half a lemon and some ice down it and turn it on. For a smelly trash can, you can make your own deodorizing disks to get rid of that nasty smell of old food. Set Daily Cleaning Goals Rather than waiting for the weekend to get your housekeeping chores done, set some daily cleaning goals for yourself. They can be simple such as making sure all of the dishes are done before you go to sleep and picking up your clothes off the floor every morning. Little tasks like this can really make a difference overall during your busy schedule. A good rule of thumb is that if it will only take a minute or two, don’t put it off. You’ll feel much better knowing it’s done rather than thinking about it all day. Do What You Can While keeping a clean house is important, it shouldn’t stress you out. Your parents probably taught you to keep your room clean and set standards for cleanliness. However, if you cannot keep up with their standards, set your own. Clean what you can and do not put pressure on yourself for your housekeeping habits. If you are too busy to clean, you’re probably too busy to think about decorating and furnishing your apartment as well.
