Mass Number (A) - Total number of protons and neutrons in the nucleus of one atom of the element.
Atomic Number (Z) - Number of protons in the nucleus of an atom.
Isotope - Element with same atomic number but with a different number of neutrons.
Ionisation Energy - The enthalpy change to remove 1 mol of electrons from 1 mol of gaseous atoms.
Relative Atomic Mass - Average mass of one atom of an element ÷ one twelfth the mass of one atom of carbon-12.
Relative Molecular Mass - average mass of one molecule ÷ one twelfth the mass of one atom of carbon-12.
Ideal Gas Equation - pV=nRT
Moles Calculation - No. of mols = mass in grams ÷ The Mr of the element/compound.
Titration Calculation - No. of mols = (volume in cm³ ÷ 1000) x the molarity
