Ionisation energy is the energy required to remove one mole of electrons from one mole of gaseous atoms. Atoms are more stable when they have full valence shells.

The ionization energy decreases from top to bottom in groups, and increases from left to right across a period.

HGence, in this trend Francium (Fr) has the lowest ionization energy.
