Electron configuration

Chemistry, oh chemistry! Chemistry is an interstmig subject. Withourt it we would not know many of the thigns we do today. However, with chemistry comes a lot of studying and hard work. There are three bonds in chemistry ionic, covalent, and hydrogen. Do not ask me why they named them this because I am unble to tell you this. However I can tell you that SCl2 is an ionic bond and NaCl is a covalent bond. Well, that is that the atoms in them form those types of bonds. Hard to belive I know, but…

What was the horsepower calculated? Does this make sense? The horsepower calculated when running up the stairs was 0.67 hp. This makes sense as 1 hp was originally defined to be the approximate amount of work a strong dray horse could do while lifting coal for one minute (The Editors of Encyclopædia Britannica, n.d). It is, therefore, reasonable to assume that a human could do 67% of this amount of work for a shorter amount of time. Generator What would happen to the force required to turn…

In today’s day and age, plastic surgery is extremely popular, especially breast augmentations. About 4% of women in America get breast augmentation each year. One of the options for breast augmentation is silicon implants. That being said I wanted to learn more about silicon and what people are putting in their bodies. Silicon is an element a pure substance that can’t be broken down. Silicon was first discovered in 1824 by a Swedish chemist named Jons Jacob Berzelius. This element is the second…

flow of electrons move towards the largest positive terminal. The reason why copper is a good conductor is because it is able to lose electrons in its outer shell, and become slightly positive. The combination of the electrons repelling each other, and their attraction towards both the slightly positive copper atoms and positive terminal lead to the electrons bouncing off of the copper atoms. This is called electrical resistance. However, at low temperatures, usually near 10 kelvin, electrons…

Gamma ray bursts (GRBs) are beams of energy in the form of gamma rays that are beamed out of the poles of a collapsing star, these are formed from very intense explosions in distant galaxies. GRBs are the brightest known electromagnetic events in the universe. They can last just a few milliseconds, or hours. The burst is often followed by an afterglow, which is emitted at longer wavelengths. We have been able to learn a lot of what we know about GRBs from afterglow. We can measure how far away…

Electrons are small negatively charged particles that are found in the electron cloud of an atom. These electrons repel other negatively charged particles and are attracted to positively charged particles. They are important because they play a major role in creating chemical bonds between atoms and contribute to its mass. A scientist by the name of Robert Andrews Millikan won a Nobel Prize for his study and finding of the charge of an electron. His findings greatly helped the scientific…

From the times of the ancient Greeks to modern day, scientist have argued the concepts behind matter. During the time of Aristotle, philosophers created scientific theories based on logic alone, eliminating all scientific evidence. This is when Democritus proposed his theory. Later, Dalton proposed his theory after completing experiments about matter. Democritus's theory was the theory of atomos. He claimed that atomos were particles so small that they could no longer be divided. Democritus…

At the water molecule occurs the covalent bond. Hydrogen has an inferior electronegativity compared with oxygen.4 Oxygen attracted the negatively charged electrons, and it makes the oxygen has a negative charge. 4 The opposite applies to hydrogen, and makes it has a positive…

contributed to the quantum theory by using Planck 's original theories to establish the idea of the photoelectric effect. This was the act of electrons emit from metals after being radiated. By observing this, he could tell the energy of the electrons by changing the frequency of the radiation. The higher the frequency, or energy level, the more electrons were…

Radiation is formed by the instability of an atom either having too many or too few of and type of particles within an atom 's.These type of particles can be either having too many or too few electrons, neutrons or protons and you have a radioactive element.The element becomes unstable as each part holds another part on so having too few means that the link may be too weak to hold it together then having too many means there pushing others off…
