Atoms are what make up what we call “matter.” They are the smallest units of a chemical element, and they consist of protons, neutrons, and electrons. These components form an atom’s subatomic particles. Before discussing the copper atom at length, we must first be able to understand the components that comprise an atom. The first of these components that make up an atom is the proton. The proton is a very important part of an atom, because the atomic number of an atom is equivalent to the…

saying that anything that has mass and can occupy space is called matter. Atoms are the main components that make up matters. Name the particles that are in different form in an atom; answer to this question is electrons, protons and neutrons. Where protons and neutrons are found in an atom? Answer: proton can be find in the nucleus, and electrons are located in the shells outside of the nucleus. Can someone in the class defines a molecule? Answer: A molecule is defined as the smallest part of a…

exactly are the properties of copper that give it its properties? An element is a chemical substance in its simplest form. An atom is the basic unit of a chemical element. An atom consists of particles such as electrons, protons, and neutrons. The protons and neutrons of the atom make up its center, called the nucleus, and its electrons surround the nucleus from a certain distance.…

15 seconds of the power going out but it took 60 seconds for the emergency generator to reach full power instead. At that point, the reactor overheated and exploded releasing radioactive decay. This nuclear meltdown was stopped by pouring lots of neutron absorbent into the reactor which stopped the fire and also the water under the reactor was drained to prevent further explosions from…

Compacted in that small space are neutrons and protons that constantly jiggle. Neutrons are uncharged particles that add mass to the nucleus without adding a charge. The protons are positively charged particles that are also located in the nucleus and symbolized as p+. The second part of an atom is the electron cloud. The electron cloud is a cloud of electron which surrounds the nucleus. The electrons are the third type of subatomic particle- along with protons and neutrons. Located…

I believe that “The Cosmological Argument” for God is still quite valid, my reasons for defending this argument have been produced after a great deal of reflection on the matter, I have concluded that the argument is still quite useful. To best describe the argument, it is the conclusion that “nothing comes from nothing” as was stated by St. Aquinas, in other words God must exist because if there was nothing then we needed something to “call it into existence” so to speak. This coincides…

Interpretation of the NOESY: (Nuclear Overhauser Effect) spectrum of 1-(2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)azepan-2-one (3a) is as follows. Strong coupling interaction of protons of 2nd and 4th position in 1-(2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)azepan-2-one (3a), was not so strongly observed in COSY because it involves long range coupling i.e. protons attached between 2nd and 4th carbon atom. Hence, we studied NOESY to know the spacial interaction between these two protons. Thus, the…

symmetry being tetrahedral in shape. On the other hand, the space group for β-FePO4 is P6422, with the lattice symmetry being hexagonal in shape. In this writing assignment, FePO4 is studied at varying temperature ranging from 294K to 1073K by neutron powder diffraction. At a relatively low temperature, it adopts the structure of the α-quartz. However, at high pressures, it changes and it can be observed that it becomes a denser octahedral structure due to a phase change occurring, which…

Paragraph 1 The structural evolution of FePO4 studied from a temperature range of 294K to 1073K by neutron powder diffraction. It is unique from α-quartz isotopes. It is different because it’s a cation is a transition metal. The structure dimensions and atomic coordinates in the α phase tend to increase by great amounts as the high-temperature β-phase rises and exhibit first order transition at 980K. The atomic structure dimensions of the α-phase FePO4 increased in a non-uniform pattern with…

The basis of Mendeleev’s periodic table was categorizing the elements according to their physical and chemical characteristics with regard to their atomic weights. Mendeleev was the first to come up with a structure for the periodic table with columns and rows. There were other scientists who have worked on tabulating information of the elements even before Mendeleev, however, he was the first scientist to come up with a periodic trend to predict the properties of elements which were not…
