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…

The space group for α-FePO4 is P3121, with the lattice 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…

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…

that it can’t be found under the finest microscopes. A tiny spec of dust contains millions of billions of atoms! Even though atoms are tiny, but it actually consist of three different particles: protons, neutrons, and electrons. In every atom, electrons move around the nucleus, the combination of protons and neutrons. The idea of an atom was first discovered by the ancient Greeks, they used the word “atomos” to describe something that is uncuttable. This idea was not found by a scientist,…

In our time and age, many inventions depend on the use of static electricity such as printers, photocopiers , pollutant removers and even spray painting. Now imagine how our world would differ if we did not have the implementation of static electricity in inventions such as photo copiers or printers. These simple inventions solve big problems. What is static electricity? How do printers work? Why do we need Printers? What are the advantages and disadvantages of the use of printers? These factors…

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…

Relative Mass Proton +1 1 Neutron 0 1 Electron -1 2. Explain the meaning of the terms, ATOMIC NUMBER and MASS NUMBER of an atom in terms of sub atomic particles. The atomic number refers to the number of protons in an atom, the mass number refers to the number of protons plus the number of neutrons (Bbc.co.uk 2015). 3. A neutral atom contains the same number of protons and electrons. Briefly explain why. If an atom is to be positively charged, it has to have more protons,…

The Atomic Theory states that all matter is composed of discrete units called atoms. The Atomic Theory started in about 400 BCE with a scientist by the name of Democritus. Democritus proposed the idea of the existence of an ultimate particle. He called this particle atomos when he was describing it, because the particle was too small to cut. Next, we get to Leucippus. Leucippus was the man who founded atomism, which is a theoretical approach that states nature consists of two principles, which…

As technology progressed so did the curiosity of the human on the theory of what made the universe. J.J. Thomson then changed the way in which atoms were understood when he discovered the electron and indirectly discovered the proton. Which led to the plum pudding model. However, this model would come under fire. Not soon after, his pupil Ernst Rutherford would disprove his model by discovering the positively charged nucleus with his gold foil experiment. The discovery of the…
