isotope
atoms of the same element with the same number of protons and electrons but different numbers of neutrons and therefore different masses
relative isotopic mass

relative atomic mass
weighted man mass of atoms of an element relative to 1/12th of the mass of an atom of carbon-12
valency
number of electrons the atom loses or gains (ionic) or the number of bonds it can form
