Vedclass · Answer

(B) Barium is an alkaline earth metal $(Group \ 2)$.It is toxic to the human body and is not required for any normal biological process.Thus,Assertion $A$ is true.Barium,like other alkaline earth metals,exhibits only one oxidation state of $+2$ in its compounds.Thus,Reason $R$ is true.However,the fact that Barium has only one oxidation state is not the reason why it is not required for biological processes; rather,it is due to its toxicity and lack of specific biological function.Therefore,both $A$ and $R$ are true,but $R$ is not the correct explanation of $A$.

Assertion $A$: Barium is not required in the normal biological processes of the human body.
Reason $R$: Barium does not exhibit more than one oxidation state.
