Question

how do the size of the atom effect ionisation enthalpy?​

Answer 1

Answer:

Ionisation energy decreases with increase in atomic size.

As a result, outer most electrons are held less firmly and lesser amount of energy is required to knock them out. For example, ionisation energy decreases in a group from top to bottom with increase in atomic size.
