How else but by experiment?
Explanation:
The first ionization energy is determined by the energy of the following reaction:
Ionization energies INCREASE across a Period (from left to right as you face the table), and DECREASE down a Group. The rationalization behind this phenomenon underlies our ideas regarding Periodicity.
