Why do we care: rocks and minerals are the basic building components of everything in our world, used for drywall, computer chips, rings, etc. Atoms: the basic building blocks of all matter: it"s divided into the nucleus [has neutrons and protons] orbited by electrons. Atomic number: how many protons are in the nucleus of an atom; it also shows where it is on the periodic table. Element: substances and materials that only contain one type of atom. 100: 5 criteria for the definition of a mineral, non-synthetic. Inorganic talks about the types of molecules it has: non-living molecules = inorganic, living molecules = organic, crystalline. Molecules that make up minerals are always formed in a very specific pattern.
