Which of the following statements about a d subshell are correct?

Question

1. Seven orbitals are present within it.
2. The maximum number of electrons it can contain is 14.
3. All electrons present have the same energy.
4. More than one of the above answers are correct.
5. None of the above answers are correct.

Answer 1

Actually, the maximum number of electrons a d subshell can hold I believe is 10. There are 5 orbitals, and each contains 2 electrons. So 5 x 2 = 10.

Answer 2

5. None are correct. There are five orbitals. The maximum electrons is 10. When filled, the orbitals split into eg and t2g levels.

Answer 3

1) is wrong because there are 5 orbitals
2) is wrong because it can house 10 electrons
3) is wrong because they can have different energies

so

the answer is 5) none of the above
