- The Atom
- Proton mass 1 charge +1
- Neturon: mass 1 charge 0
- Electron: mass 1/2000 charge -1
- Mass number - total number of protons + neutrons
- Number of neutrons: mass number - atomic number
- Isotopes: atoms with the same number of protons but different number of neutrons
- The relative atomic mass of an element is the weighted average mass of an atom of that element divided by 1/12 the mass of a carbon-12 atom
- Relative isotopic mass: mass of an atom of an isoptope of an element on a scale where an atom of carbon - 12 is 12
