The ionization energy will be maximum for — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

Ionization enthalpy of hydrogen (H), lithium (Li), beryllium (Be), and boron (B) in -1 kJmol is 1312, 520.2, 899.5, and 800.6 respectively. Hydrogen has the maximum ionization energy due to the presence of a single electron and small radius. Therefore, the correct option is a.
