Elements of group 14 (a) exhibit oxidation state of +4 only (b) exhibit oxidation state of +2 and +4 (c) form \mathrm{M}^{2-} and \mathrm{M}^{4+} ion (d) form \mathbf{M}^{2+} and \mathbf{M}^{4+} ions
Elements of group 14 (a) exhibit oxidation state of +4 only (b) exhibit oxidation state of +2 and +4 (c) form \mathrm{M}^{2-} and \mathrm{M}^{4+} ion (d) form \mathbf{M}^{2+} and \mathbf{M}^{4+} ions

Solution:

(b) Group 14 components have 4 valence electrons. Thus, bunch oxidation status is +4. In any case, the lower oxidation state turns out to be progressively steady because of the inactive pair impact, and the higher oxidation state turns out to be less steady.
Accordingly, this gathering shows +4 and +2 oxidation states.
