The `+1` oxidation state is more stable than `+3` oxidation state for thallium. Give reason.

Why is+2oxidiation state of lead more stable than +4 oxidation state?

The oxidation state of -3 is least stable in

Account for the following: The +2 oxidation state of lead is more stable than +2 oxidation state of Tin.

Manganese in the +2 oxidation state is more stable than +3 oxidation state where as iron is stable at +3 oxidation state than +2 oxidation state. Explain why

Explain, why is the +2 oxidation state of lead more stable than the +2 oxidation state of tin.

In which case +1 oxidation state is stable than +3 :

The oxidation state +1 is more stable is thallium. Why?
