The correct Answer is:
To determine whether the statement "Pairing of electrons in degenerate orbitals takes place only when the degenerate orbitals are filled with one electron each" is correct, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Degenerate Orbitals**: - Degenerate orbitals are orbitals that have the same energy level. For example, in the p subshell, we have three degenerate orbitals: 2px, 2py, and 2pz. 2. **Recalling Hund's Rule**: - Hund's rule states that electrons will fill degenerate orbitals singly before pairing occurs. This means that each orbital will receive one electron before any orbital gets a second electron. 3. **Applying Hund's Rule to the Question**: - According to Hund's rule, pairing of electrons in degenerate orbitals (like the 2p orbitals) occurs only after each orbital has one electron. Thus, the statement suggests that pairing occurs only when each degenerate orbital has one electron. 4. **Conclusion**: - Since Hund's rule supports the idea that pairing occurs only after all degenerate orbitals are singly occupied, the statement is indeed correct. ### Final Answer: The statement "Pairing of electrons in degenerate orbitals takes place only when the degenerate orbitals are filled with one electron each" is **true**.
