Elements of group 14
A. exhibit oxidation state of + 4 only
B. exhibit oxidation state of + 2 and + 4
C. form M2– and M4+ ions
D. form M2+ and M4+ ions
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.
