उत्तर

Elements of group 14 exhibit oxidation state of +2 and +4.

Explanation:

The elements of group 14 have 4 valence electrons. Therefore, the oxidation state of the group is +4. However, as a result of the inert pair effect, the lower oxidation state becomes more and more stable and the higher oxidation state becomes less stable. Therefore, this group exhibits +4 and +2 oxidation states

Group 14 element Oxidation state
C +4
Si +4
Ge, Sn, Pb +2, +4
