MCQ
From Be to Ra, ionization energies:
  • A
    Increases
  • B
    Decreases
  • C
    Remain same
  • D
    None of these

Answer

  1. Decreases

Explanation:

Be to Ra,

As we go down the group in Periodic table, atomic size increase, Nuclear hold on electron decrease for an outer electron.

Thus, Ionization energy decreases down the group.
