What is ionization energy? how does it vary in period of the periodic table?

Answered by admin @



It is defined as “the amount of energy required to remove the loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation”


Ionization energies increase across a Period, and decrease down a Group.


Hope it helps
