Given below are two statements: Statement I: Two electrons can have the same value of three quantum numbers ( n , l ) and m in same atom. Statement II : No two electrons in an atom can have, the same set of four quantum numbers. In the light of the above statements, choose the most appropriate answer from the options given below:

Step-by-step solution

- Statement I: Two electrons in the same atom cannot have the same values of three quantum numbers (n, ), and (m ). This is incorrect because of the Pauli exclusion principle, which states that no two electrons can have the same set of four quantum numbers, including the spin quantum number (s ). - Statement II: No two electrons in an atom can have the same set of four quantum numbers. This is correct as per the Pauli exclusion principle.
