ATOMS (A short history of the knowledge of the atom) Compiled by Jim Walker. Originated: Sept. 1988 Latest revision: Nov. 2004. atom n. A unit of matter, the smallest unit of an element, consisting of a dense, central, positively charged nucleus surrounded by a system of electrons, equal in number to the number of nuclear protons, the entire structure having an approximate diameter of 10-8.

When different elements (different types of atom) react and combine to form a compound (new substance) chemical bonds must be formed to keep the atoms together. Once these atoms are joined together its usually difficult to separate them. The atoms can join together by sharing electrons in what is known as a covalent bond. Or, they can transfer or accept electrons to form positive and negative.
