Question

Arrange the following elements in their increasing order of ionization energies:
O,S,Se, Te,Po.

• A. Se,Te,S,Po,O
• B. O,S,Se, Te,Po
• C. Po,Te,Se,S,O
• D. Te,O,S,Po,Se

Answer 1

The correct option is C Po,Te,Se,S,O

Down the group ionization energies decreases
So, the increasing order of ionization energies in the 16th group is Po,Te,Se,S,O.
