Describe the parts of an atom, and what they do.

An atom is the smallest unit of a chemical element and is considered to be the basic building block of matter. It consists of protons, which carry a mass of one atomic mass unit and has a positive charge and contributes directly to the atomic number, electrons, which have a mass considered to be negligible and carry a negative charge, and neutrons, which have a mass only slightly larger than that of a proton and have no charge, and contribute to the many isotopes that an element can have.
