Question

Use the periodic table to answer the given question, Identify an element that would tend to gain two electrons.

Answer 1

An element is likely to gain two electrons if it needs only two electrons to attain the stable noble gas configuration.

Thus, the general electronic configuration of such an element should be ns2 np4.

This is the electronic configuration of the oxygen family i.e O(2p4), S(3p4), Se(4p4), Te(5p4), Po(6p4), Uuh(7p4).
