Relative isotopic mass
Mass of an individual isotopes relative to the mass of Carbon-12
3 of 15
Relative atomic mass
Average mass of an elements isotopes relative to the mass of Carbon-12.Where Carbon-12 has a mass of 12
4 of 15
First ionisation energy
The energy required to remove one electron from each atom in one mole of gaseous atom to form gaseous 1+ ions
5 of 15
Isotopes
Atoms with the SAME number of protons but DIFFERENT numbers of neutrons
6 of 15
Avogrado's number
Number of atoms in 12g of Carbon-12

Empirical formula
The simplest whole number ratio in which the atoms in a compound combine together
10 of 15
Molecular formula
A formula that tells us the number of atoms each

Dative covalent bond (coordinate)
A covalent bond formed when both shared electrons are provided by only one atom. The donor atom must have a lone pair.
