Ionisation energy trend in Group 2 As you go down the group first ionisation energy decreases because: - Although nuclear charge is increasing - The electrons have an extra quantum shell of shielding making them easier to remove - They exist in a higher energy orbital (and/ or a further distance from the nucleus) Reactivity trend in group 2 Group 2 elements become more reactive going down a group as the outer two electrons are easier to remove because they have lower first ionisation e...
