Vedclass · Accepted Answer

$A$ and $R$ are both true but $R$ is not the correct explanation of $A$.

Vedclass · Answer

(B) Statement $A$ is based on the Pauli Exclusion Principle,which states that no two electrons in an atom can have the same set of four quantum numbers. This implies that an orbital can hold a maximum of two electrons with opposite spins.Reason $R$ is also a true statement because electrons have spin angular momentum,which generates a magnetic moment. Electrons with opposite spins produce magnetic fields that are oriented in opposite directions.However,the reason $R$ is not the direct explanation for why an orbital can only hold two electrons; the Pauli Exclusion Principle is the fundamental reason. Therefore,both statements are true,but $R$ is not the correct explanation of $A$.

Statement $A$: An orbital can accommodate a maximum of two electrons.
Reason $R$: Two electrons in an orbital produce opposite magnetic fields.
