Question

Find out why the variation in ionizing energies along the periodic table and down the group.

Answer 1

Answer:

Reason : It is due to the increase in the distance between the valence electrons and the nucleus as the atomic size increase down a group, the force of attraction between the nucleus and the valence electrons decrease, therefore, the energy required to remove the electrons, i.e., the ioisation energy goes on decreasing .

Answer 2

Answer:

The ionization energy is different for electrons of different atomic or molecular orbitals. ... Conversely, as one progresses down a group on the periodic table, the ionization energy will likely decrease since the valence electrons are farther away from the nucleus and experience greater shielding.
