Question

wt happens to ionisation down group and right period
​

Answer 1

Ionization energy decreases from top to bottom in a group.

Reason: While going down a group, atomic size increases, hence easy to remove an electron. So less ionization energy

Ionization energy increases from left to right in a period.

Reason: atomic size decreases and nuclear pull increases. So difficult to remove an electron.

Answer 2

hi there..

ionisation decreases down a group and increase along a period,i.e, increase from left to right.

hope this helps..
