Assertion : Two electrons in an atom can have the same values of four

1.	Assertion : Two electrons in an atom can have the same values of four quantum numbers. Reason : Two electrons in an atom can be present in the same shell, sub-shell and orbital and have the same spin.A. If both assertion and reason are true and the reason is the correct explanation of the assertionB. If both assertion and reason are true but reason is not the correct explanation of the assertionC. If assertion is true but reason is falseD. If the assertion and reason both are false
Answer» Correct Answer - D We know from the Pauli exclusion principle, that two electrons in the same atom can not have same value of all four quantum numbers. This means each electron in an atom has only one set of values of n,l,m and s. Therefore both the Assertion and Reason are false.
