Document Summary
Chapter 2: list two characteristics an earth material must have in order to be considered a mineral, naturally occurring, generally inorganic, solid, orderly crystalline structure, definite chemical composition, define the term rock. Rocks are more loosely defined as aggregates of different minerals. The number of protons is the same as the element number: neutron particle in the nucleus of the atom. It has no charge associated with it: electron negatively charged particle that orbits the nucleus. The valence shell of an atom is its outermost shell and responsible for bonding with other atoms. An atom does not have a charge because it has an equal number of protons or electrons. An atom that has given up one or more valence electrons becomes a positive ion. An atom that has taken on extra valence electrons becomes a negative ion: briefly distinguish among ionic, covalent, and metallic bonding and describe the role that electrons play in each.
