Elements of group 14
The elements of group 14 have 4 valence electrons. Therefore, the oxidation state of the group is + 4. However, as a result of 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 |
