Document Summary
Rock: a solid aggregate of the grains of 1 or more minerals. By definition a mineral is: naturally occurring, inorganic solid, has an ordered internal molecular structure. It will grow into crystals given enough time and space: definite chemical composition, ex pyrite is fes_2. Elements: basic building cocks of minerals, over 100 are known. Atoms: smallest particles of matter, retains all the characteristic of an element. Nucleus: center of atom, consists of protons (+) and neutrons (-, mass number is sum of neutrons and protons in an atom. The number of protons is always the same for a particular element: ex carbon always has 6 protons. The number of neutrons, however, can vary. Electrons: negatively charged [articles that surround the nucleus, orbit nucleus at given distance (shells) Minerals consist of an orderly array of atoms chemically bonded to form a particular crystalline structure. Internal atomic arrangement is determined by atomic size.
