Atom

lives. These particles are called atoms, and they are the most basic and indivisible units of matter. They retain their identity through chemical reactions, yet they are so small that even the strongest microscope cannot detect them. The reasoning behind atomic reactions intrigued many intellectuals. To understand more about this concept, they had to comprehend the compositions of these particles. Although the scientist and philosophers could not examine individual atoms, they still were able to…

philosophy put forth by the pre-Socratic philosophers Leucippus and Democritus. Some main points of the atomists readings that I am going to write about in this paper include the different characteristics of the atom, the empty space these atoms move around in, and how we perceive these atoms. Overall, I feel like the atomist have a very good base of ideas for their time. However, there are a few ideas that can be considered dated. I will expand on that in in the first few paragraphs of this…

In Memory of John Dalton 1766-1844 John dalton,son of Joseph and Deborah dalton, he had one brother named Jonathan no sisters.John dalton lived and worked in England as a teacher and a public lecture.He wa very interested in meteorology for the longest.He published meteorological observations and essays which he recorded.He did so many things, he made his own atomic theory he was also was very interested in color blindness.His serious interest in this led him to the view of atomism. Between…

know there are such things as atoms? The short answer is that they don’t. No one has ever seen an atom. However, there are many more ways to show that something could exist than to have ‘seen something’. The idea of the atom has been hypothesised since around 440BC, but the idea has only been widely accepted since the early 19 century, when the atomic theory was first proposed. Since then, our understanding of the atom has significantly developed. But why is the atom so widely accepted in…

Covalent bonding occurs when atoms share pairs of electrons. Atoms will covalently bond with other atoms in order to gain more stability, which are gained by forming a full electron shell. By sharing their outer most valence electrons, atoms can fill up their outer electron shell and gain stability (Chem wiki) Nonmetals will readily form covalent bonds with other nonmetals in order to obtain stability, and can form anywhere between one to three covalent bonds with other nonmetals depending on…

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…

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 are atom and void. After Leucippus came…

3.2. Molecular Electrostatic Potential (MEP) surface of Pyrazolooxazines. The correlation between the molecular structure and the physicochemical property of molecules, including biological molecules and MESP-based drugs, to distinguish electron rich zones (electrophilic attack) from electron-poor ones (a nucleophilic attack) 16, 17. We represent in this study the molecular surface of the electrostatic potential (MESP), the electrostatic potential (ESP) and the electron density (ED). MESP is a…

This essay going to be about an atom. Atom is always around us all the time and ever object are made out of an atom. We, humans, are also made of the atom. Knowing about the structure and what it really is a very important thing to learn as a student. In order to learn about an atom, we will have to understand about Democritus first. So who is Democritus? Democritus is the first human to ever come up with the first atomic theory. Democritus was born in Greece around 460BC. He has a life spend…

to high melting points. Magnesium bromide has a melting point of 1,312 degrees Fahrenheit and 711 degrees celsius. It is soluble in water and is conductive.Within this ionic bond, there are two bromine atoms and one magnesium atom. One of magnesium’s valence electrons go to each of the bromide atoms, which creates a balance between protons and electrons. (Figure 1) When interpreting the lewis structure for Magnesium Bromine, it is important to understand the charges of each of the elements.…
