Question

The Pauli exclusion principle applies to the following option.

• A. H
• B. H\(^+\)
• C. H\(^-\)
• D. He\(^+\)

Hint:

Pauli's exclusion principle is fundamental for understanding the electronic configuration of multi-electron atoms. It governs the maximum electron capacity of atomic orbitals.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Pauli's exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers. It applies to systems with at least two electrons.

Step 2: Detailed Explanation:
• H: Has one electron. Principle does not apply as it deals with the arrangement of multiple electrons. • H\(^+\): Has zero electrons. Principle does not apply. • H\(^-\): Has two electrons. The principle applies to the configuration of these two electrons. • He\(^+\): Has one electron (since He has Z=2, He\(^+\) has one electron). Principle does not apply.

Step 3: Final Answer:
H\(^-\) is the correct answer, which corresponds to option (C).
