Assign reason for the following: (a) Noble gases are mostly inert (b) Bismuth is a strong oxidising agent in pentavalent state.

Answer»

Solution :(a) It is DUE to stable electronic configuration and high ionisation POTENTIAL of noble gases.
(b) Bi(+3) is more stable than Bi(+5) due to INERT pair effect. That is why Bi(+5) gains two electrons to form Bi(+3) and acts as an oxidising agent
`Bi^(5+) + 2e^(-) to Bi^(3+)`
