Glossary term: Atomic Structure

Description: Atomic structure is the internal organization of the particles within an atom. It tells you how many neutrons and protons can be found in the nucleus of an atom and describes how each of these particles is made up of quarks. It also shows that the electrons are in permanent motion around this nucleus, at different levels according to their energy. Atoms are electrically neutral because they have the same number of electrons and protons. An atom can get charged by losing or absorbing an electron, in which case it becomes an ion.
