Q

Atomic size

A

increases down the group, decreases across the period

as more energy levels are available, size will increase; as nuclear charge increases, decreases across period(charge pulls closer together to make it smaller)

Q

lattice energy

A

decreases down the group, increases across the period

size of cations and anions smaller across the period from increasing nuclear charge

distance between elements can have a high energy for smaller distances
