The steric number formula defines the number as the sum of the number of atoms bonded to the central atom of the molecule and the number of lone pairs of electrons around it. To find the steric number for a molecule, draw its Lewis structure, then count the number of bonded atoms and lone pairs.

Bond energy is defined by the sum of all of the bonds broken minus the sum of all of the bonds formed: ΔH = ∑H (bonds broken) - ∑H (bonds formed). ΔH is the change in bond energy, also referred to as the bond enthalpy and ∑H is the sum of the bond energies for each side of the equation.

The order of filling orbitals. Electrons fill low energy orbitals (closer to the nucleus) before they fill higher energy ones. Where there is a choice between orbitals of equal energy, they fill the orbitals singly as far as possible. The diagram (not to scale) summarises the energies of the various orbitals in the first and second levels.
