Atom Egoyan

Jean de Dieu Kamiri Professor Steven Phil 1301 02/08/2018 Title: Thales vs. Homer Abstract: Thales is the Greek philosopher, he is the first person to investigate the basic principles, the question of the substance of matter, and he foundered the school of natural philosophy. He is in among seven sages of Greece. He did research almost all areas of knowledge, mathematics, politics, history, science, engineering, and philosophy. He suggested concepts to explain many of the events of nature, the…

Electromagnetic waves are a type of radiation that is produced from electrons (negatively charged particles) and x-rays is a type of electromagnetic wave. The shorter the wavelength of a wave, the more energy the wave emits. Gamma radiation has the shortest wavelength amongst all the other electromagnetic waves and has the most energy. It cannot be seen or felt and can pass through almost anything. X-rays have slightly longer wavelengths than Gamma rays and has the second most energy emission.…

electrons from atom to atom and molecule to molecule. This is because the electrons are tightly bond to the atoms leaving no space for there to be any free electrons to transmit electrical energy. Examples of insulators are glass, rubber, wood and paper. Conductor is an object or type of material that can transmit heat, sound, light or electricity. It does this by allowing electrons to flow freely from particle to particle. This is because the electrons can detach from their atoms and zip around…

Minoxidil, an antihypertensive vasodilator medication, which was developed in the 1950’s by a company called Upjohn originally used to treat ulcers. During their experiments with dogs, they figured out that it did not cure ulcers, but acted as a vasodilator. Due to this recent discovery, Upjohn was able to develop a compound called Minoxidil in 1963 as well as being able to synthesize over 200 variations of the compound. The molecular structure and compound of Minoxidil is C9H15N50, made…

made of a single type of atom, which cannot be broken down into anything smaller. Inside an atom are the subatomic particles protons (positively charged) and neutrons (neutral), and outside are the electrons (negatively charged) that orbit the atom in an electron cloud. When two or more atoms of an element or elements bond together, they form a compound. Depending on the type of elements, there are different kinds of bonds that could form. Ionic bonds form between the atoms of at least one…

2.1 New semi empirical formula for of mass attenuation and energy absorption coefficients Most of the tissues of human organs consisting of elements such as H, C, N, O ,Ca ,P, Na, Mg, S, CI ,K ,Fe and I in their elemental composition. We have studied the variation of mass attenuation and energy absorption coefficients with atomic number at different energies for the elements which are constitutes of tissues of human organs. It has been proposed the empirical relations for mass attenuation and…

Alchemy was the earliest understanding of today’s chemistry. These two display Is Alchemy Chemistry? different pathways of thinking and rationalising rather than two diverse concepts. The practice of alchemy is the basis of chemistry, as it was a vital role of origin and evolution towards chemistry we know today. The comprehension of both alchemy and chemistry will aid in order to establish their connections and difference of opinion or belief. Discovering both histories of the two concepts will…

here first and second term in the equation (3) represents coulomb potential whereas last term is exchange-correlation potential. The exchange and correlation effects were taken in to account by using PBE-sol exchange correlation technique for treatment of electronic interactions in ZnGa2S4 and CdGa2S4 crystal compounds. The aim behind adoption of PBE-sol exchange correlation technique is that it recoups the prime gradient expansion for exchange and jallium surface potential are exactly…

about the model of the atom before Thomson and Rutherford conducted their experiments? The first model of the atom is thought to have come from two Greek philosophers - Democritus and Leucippus – in the fifth century BC. These two philosophers believed that everything was made up of matter, and that you could half a given portion of matter (and keep halving the product) and eventually be left with something that couldn’t be halved again: the atom. They believed that all atoms were imperishable…

Electron Motion Control and Imaging M. Th. Hassan Electron motion in atomic systems, which happens on timescales of attoseconds (10-18s), is at the heart of all phenomena in nature. For instance, the motion of electrons in the chemical bonds determines the structure change in the molecules. Therefore, controlling this fast electron motion, in turn, allows to control the molecular structure change. Additionally, recording snapshots of the electron motion will provide real-time access to all…
