Explain why the highest oxidation state for group 14 (IVA), +4, is exclusively observed for carbon but hard to stabilize for lead, which has +2 as its most stable oxidation state. When formulating your answer, also consider what oxidation states are typically exhibited by silicon, germanium and tin.
