Atomic nature of matter: atomic theory: all material substances are composed of tiny units called atoms; chemical processes are just the separation and re-mixing of the different kinds of atoms. Most substances are made of different kinds of atoms so they can be separated into simpler substances. Elements: substances that are composed of only one kind of atom, 92 are natural: parts of the atom: proton (positively-charged), electron (negative), neutrons (neutral) Number of electrons and protons will always be the same. Atomic number: number of protons in the nucleus of an atom (z) Atomic mass number: sum of protons and neutrons in the nucleus a = n+z. Dilute solution: small amount of solute in a solvent.
