The energy required for an element to ionize and helium has the lowest.
Francium and cesium
the lowest ionization energy in IA :hydrogen ,lithiun ,sodium and potassium
Metals have the least ionization energy
Rb
This energy is called ionization energy and is different for each chemical element.
Helium has the highest ionization energy.
