define ionisation energy
energy required to remove 1 mol electrons from 1 mol gaseous atoms to form 1 mol gaseous unipositive atoms
What four things impact ionisation energy
atomic radius, nuclear charge, shielding, orbital pairs
what trends do ionisation energies have (3)
decrease down groups, increase across period, change in shell
