10 questions from this quiz
Energy to remove 1e⁻ from 1 mol gaseous atoms
Ionisation is endothermic - energy supplied
Decreases it - greater distance weakens pull
Less e⁻-e⁻ repulsion; stronger nuclear pull
Electron removed from inner, closer shell
Decreases - radius & shielding increase most
Generally increases - more protons, same shell
2p e⁻ in B is higher energy than 2s in Be
Paired e⁻ in O repel, easier to remove one
One from highest energy level (outer shell)
