a) What general trend of the oxidation states does this observation illustrate?
b) What could you suggest as an explanation for this observation?
(a) The general trend of the oxidation states indicate that for group 4A elements, the +4 oxidation state can exist for all elements, but it may not necessarily be the most stable. Silicon is stable at +4 and is covalent. Lead can exist with an oxidation ...
