CHXI02:STRUCTURE OF ATOM
307344
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.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Pauli's exclusion principle asserts that no two electrons in an atom can share the same set of all four quantum numbers, preventing more than two electrons in an orbital and necessitating opposite spins if an orbital hosts two electrons. So option (1) is correct.

The below configuration is not correct as it violates
1 Only Hund’s rule
2 Only Pauli’s exclusion principle
3 \({\rm{(n + l)}}\) rule
4 (Hund + Pauli) rule
Explanation:
According to Pauli's exclusion rule, no two electrons can have same four quantum numbers. In s-orbital, 2 electrons have same spin quantum number. According Hund's rule, electrons are first singly filled in each orbital with parallel spin then pairing starts which violates in p - orbital.

Two electrons occupying the same orbital are distinguished by
1 Principal quantum number
2 Azimuthal quantum number
3 Magnetic quantum number
4 Spin quantum number
Explanation:
Two electrons present in same orbital will have same principal, azimuthal and magnetic quantum numbers. These electrons differ in spin quantum numbers, \(\mathrm{+\dfrac{1}{2}}\) and \(\mathrm{-\dfrac{1}{2}}\)

Which of the following orbital diagram violates Pauli's exclusion principle?
1
2
3
4
Explanation:
According to Pauli's exclusion principle, within an orbital, the electrons must have opposite spin. Therefore, violates this principle
