Ionisation energy increases as we move down the group of a periodic table whereas it decreases as we move from left to right of the periodic table.
Ionisation energy increases as we move down the group of a periodic table whereas it decreases as we move from left to right of the periodic table.
The correct option is B False
The ionisation energy is the amount of energy required to liberate the loosely bound electron from the outermost shell of an isolated gaseous atom of an electron
Ionization energy decreases as we move down a group due to the increase in the size of the atom(Addition of new shell along the group). Thus, the distance between the valence electron and the nucleus increases making it easier to remove the valence electron. Thus, less amount of ionisation energy is required for removing this electron away from the atom.
Ionisation energy increases when moving from the left to right side of the periodic table due to decreasing atomic size. Electrons are filled in the same shell in this case.
