Which of the following elements has the lowest ionization potential ?

The energy required to pull the most loosely bound electrons from an atom is known as ionization potential. It is expressed in electron volts. The value of ionization potential depends on three factors :(i) the charge on the nucleus (ii) the atomic radius and (iii) the screening effect of inner electron shells.
