Captain Atom

The atomic number to my element is 11, the mass number is 23, the number of neutrons is 12, the protons are 11 and the electrons are also 11, the electron configuration of my element is 1s22s22p63s1. The person who discovered my element is Humphry Davy. He discovered sodium in 1807. Origin of sodium is derived from the English word ‘soda’. The appearance of sodium is soft metal that tarnishes within seconds of being exposed to the air. It also reacts vigorously with water. Used as a…

The purpose of the experiment, “Charge to Mass Ratio for an Electron”, was to measure the charge-to-mass ratio (e/m) for an electron. This lab was performed to help students further understand the characteristics of an electron in regards to various things such as its magnetic field strength and velocity. By using a Daedalon (e/m) Apparatus paired with Helmholtz coils and a glass bulb filled with helium gas, students were able to observe electrons travelling in a circular path. This is due to…

7. If during the experiment an air bubble leaked into the eudiometer tube while it was being inverted in the water bath than the measured volume of hydrogen gas would be off. Ultimately the measured volume of hydrogen gas would be too high because the gas being recorded would not only include hydrogen gas, but the air that leaked into the eudiometer as well. Because the volume of hydrogen gas would be too high the calculated molar volume of hydrogen would also be too high. This is because to…

James Chadwick was born October 20th, 1891 in Bollington, United Kingdom. His parents were John Chadwick and Anne Mary Knowles. He attended Manchester High School and Manchester University (James Chadwick – Biographical, Nobelprize.org). While he was at Manchester University he worked on a research project in Earnest Ruthford’s laboratory. Chadwick finished his project successfully and graduated with first class honors in physics in 1911. He continued to work in Earnest’s laboratory until in…

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…
