Group 4 element - Wikipedia
Thermal stability of oxides in +2 and +4 oxidation states. Note that +4 oxidation state is more thermally stable than +2 for ALL the group IV elements EXCEPT lead. At lead, the situation reverses and the +2 is MORE thermally stable than the +4 oxidation state. This stability occurs for the aqueous ions as well.
