Magnesium Magnesium is one of the best elements you can own it’s a 3rd period element its part of the alkaline earth metal family. Magnesium is a metal and it’s a solid, with a isotope of 24 and really high energy level. Buy magnesium it’s going to be your favorite purchase you will ever make you won’t regret it. Magnesium was discovered in 1808 by a guy named Sir Humphrey Davy but it was first experimented by joseph black. The Country it was discovered in was England in the United Kingdom.…

Pure metals are of very less application in engineering as of the need of conflicting property requirement. For e.g. an application may need a material that is both hard and ductile, there is no any such kind of substance existing in nature. For this present problem, combination (in liquid state) of one material with other material is used. This mixing of materials in the molten liquid state is termed alloying ,that provides a property that is not similar to the original materials. Bronze…

We would like to begin by stating our sincere gratitude towards you and your company for giving us the opportunity to help analyze your data from the Photoelectron Spectroscopy (PES) instrument. Our job was to complete five main tasks. We fixed your corrupted data of chlorine with a new one of our own. We expanded your portfolio so you have the PES of the elements Titanium and Vanadium, while also providing a full analysis of all of the elements that were tested. We discovered a pattern in which…

Dawkins decides to bring a little chemistry into this chapter. He brings up the Bohr model, he states atoms being similar to the solar system. The way electrons go around the nucleus is the same way planets orbit. Elements have the ability to be present even with a varying number of neutrons. This is to be called isotopes. His point with this is that these isotopes are very balanced while others may be not so balanced. This will then be called radioactivity. Every isotope that becomes…

are absorbed are determined by the electrons in a compound.1 As electrons move around, they can absorb energy and become excited. The energy, and thus the wavelength of light, the electrons absorb is determined by the type of atoms found in the compound and how those atoms are bound together. Different environments for electrons will also determine how much of a particular wavelength of light can be absorbed, a parameter which is reflected…

the sample. The characteristic of backscattered is high energy and close to the energy of incident electron, the resolution is low. On the contrary, the energy of secondary electrons is very small and less than 50eV, incident electrons and sample atoms can scatter several times which is limited. As a result, it does not spread to other direction. We can see the figure 1 to realize how they worked. When we get the image caused by backscattered, we can notice that the image is not very clear, and…

would have otherwise died without. A hydrogen bond is the electromagnetic attraction exerted between polar molecules where hydrogen is bound to a larger atom. An example of this would be a hydrogen atom bonding to an oxygen or nitrogen atom. A water molecule is formed by 2 negatively charged hydrogen atoms attaching to a positively charged oxygen atom. This is why hydrogen bonding is such an important concept in The Martian. Mark Wattney had to use hydrogen bonding to create water. Wattney knew…

Introduction A reaction in organic chemistry that involves a simultaneous 3 pi bond shift is Diels-Alder cycloaddition, where a conjugated diene and an alkene with an electron withdrawing group (a dienophile) will react to form two carbon-carbon single bonds at the expense of the one carbon-carbon multiple bond to most often form a 6 membered ring adduct (Ketcha, 106). A conjugated diene is a hydrocarbon the contains two carbon-carbon double bonds and a dienophile also means “diene-loving”…

machines are large, tube-shaped magnets. An MRI scanner contains two powerful magnets, which represent the most critical part of the equipment. The human body is largely made of water molecules, which are comprised of hydrogen and oxygen atoms. At the center of each atom lies an even smaller particle called a proton,…

Fluorite, also called fluorspar, is a mineral that is composed of calcium and fluorine. Pure fluorite is colorless. Fluorite is known as the most colorful mineral in the world. Each colored fluorite has its own name. The most common colors for fluorite come in purple, blue, yellow, or green (King, Fluorite.) What makes fluorite colorful depends on what elements are substituting calcium in the crystalline structure. Fluorite is an interesting mineral because of its wide range of uses. People use…
