In the given which principle is stated as “ No two electrons in an atom can have the same set of all four Quantum numbers ‘’

For ant two electrons in an atom, the set of all four quantum numkber can be same

Assertion : An orbital cannot have more than two electrons, moreover, if an orbital has two electrons they must have opposite spins. Reason : No two electrons in an atom can have same set of all the four quantum numbers.

How many electron in a given atom can have the following quantum number

The rule which states that no two electrons can have same value of all the four quantum number is

STATEMENT-1: An orbital cannot have more then two electrons and they must have opposite spins. STATEMENT-2: No two electrojns in an atom can have same set of all the four quantum numbers as per Pauli's exclusion principle.

Assertion (A) : An orbital cannot have more than two electrons, more over if an orbital has two electrons they must have opposite spins. Reason (R) : No elements in an atom can have same set of all four quantum numbers.
