understanding of the structure of the atom, scientist were able to isolate system of electrons and atomic nucleus. The atomic part of physics is primarily concerned with the arrangement of electrons around the nucleus and the processes by which the arrangements was changed. Atomic theory has affected the field of physics in a way that has given scientist knowledge on how to produce an atomic bomb. Scientists has differentiated between atomic physics that deals with the atom as a system involving…

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.…

Atomic Theory The atom is the smallest unit of an element. It is composed of two main parts. The nucleus is the central point of an atom. 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…

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…

scanning a sample with a focused beam of electrons. Samples can be observed in high vacuum, low vacuum, in wet conditions, or at elevated temperatures. The images in this paper were obtained by the detection of secondary electrons that were emitted by atoms excited by the primary electron beam. The primary beam scans in a raster fashion, making horizontal passes across the x-axis one at a time. This allows the detector to display the information into the image on pixel at a time in synchronized…

Experiment #6: Polarimetry Resolution of (∓)-Racemate: (∓)-ɑ-Phenylethylamine OBJECTIVE All chiral molecules have a mirror image of themselves. While they have the same physical properties, they interact with other chiral molecules completely different. Since there are many chiral molecules in organics, this can lead to the need to make optically pure products. If the chemist does not, it can lead to many problems including death. In this experiment, the separation of two enantiomers was…

C-H bonds are considered nonpolar. This is because the electronegativity of C is 2.5 and the of H is 2.1, putting their electronegativity in the nonpolar range. O-H bonds are more polar than N-H bonds. This is because the O-H bond is more electronegative because the electronegativity of O is 3.44 while the electronegativity of N is only 3.04.

Ivacaftor, C24H28N203, is a 4-oxoquinoline-3-carboxamide molecule which consists of five main functional groups: a quinolone, an amide, a phenol, and two tert-butyls. Quinolones are regularly found in anti-biotics, amides are seen in the synthesis of nylon, phenol can be retrieved from coal tar, and tert-butyl groups are big hydrophobic groups found in tert-butyl alcohol (the simplest tertiary alcohol); none of these functional groups were invented or developed first by the parent company of the…

Empirical Formula of Magnesium Oxide Introduction Chemical formulas imply the arrangement of compounds. Empirical formulas are the simplest whole number ratio of the elements present in a compound (Owen, 2014). However, the actual amount of each type of atom that a compound is consisted of is called the molecular formula. For that reason, the deduction of the empirical formula and the molar mass of a compound is required to determine the molecular formula of the compound. To determine the…

1.1 Introduction: Both living and non-living things are composed of molecules made from chemical elements such as Carbon, Hydrogen, Oxygen, and Nitrogen. The organization of these molecules into cells is one feature that distinguishes living things from all other matter. The cell is the smallest unit of matter that can carry on all the processes of life. The three principles define cell theory: 1. All living things are composed of one or more cells. 2. Cells are the basic units of structure and…
