Select all the true statements. The highest oxidation state of elements in Groups 3A through 7B is +3. First ionization energy values generally increase down a transition group. The transition elements in a period show a steady increase in electronegativity. In the transition series, atomic size across a period decreases at first but then remains relatively constant. Ionic bonding is more prevalent for the higher oxidation states and covalent bonding is more prevalent for the lower states.

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.
