Why does increasing nuclear charge lead to higher ionisation energy?
Stronger attraction to outer electrons
What effect do inner electrons have on ionisation energy?
What effect do inner electrons have on ionisation energy?
Shield outer electrons, reducing energy
What happens to first ionisation energy down a group?
What happens to first ionisation energy down a group?
