Document Summary
Mineral: a naturally occurring, inorganic, solid element or compound with a definite composition and regular internal structure. Can consist of just one element (i. e. diamond) or of several elements. Two or more elements combined are referred to as a compound. Simple or complex, each mineral has a definite chemical composition or at least a definite range in composition. When broken down to their most basic form, elements are made up of one or more atoms. Atoms are composed of a nucleus containing neutrons, which are neutral charge, and protons, which are positive charge. Orbiting the nucleus are electrons, which are negatively charged. Depending on the overall ratio of protons to electrons, an atom may be positively or negatively charged. Generally, opposite charges attract, while negative charges repel. Minerals consist of an orderly array of atoms chemically bonded to form a particular crystalline structure. Minerals form when atoms bond through ionic, covalent, or metallic bonding.
