Answer is Right!
Answer is Wrong!
The correct answer is: D. 10
A d-orbital is a type of atomic orbital with an angular momentum quantum number of 2. It can accommodate up to 10 electrons.
The d-orbitals are located in the third shell of an atom, and they are shaped like dumbbells. They are degenerate, which means that they have the same energy.
The d-orbitals are important because they are involved in many chemical reactions. For example, the d-orbitals of iron are involved in the formation of the heme group in hemoglobin.
The d-orbitals are also important in the formation of coordination complexes. For example, the d-orbitals of cobalt are involved in the formation of the cobalt(II) hexacyanidoferrate(II) complex.
Here is a brief explanation of each option:
- Option A: 3. This is incorrect because a d-orbital can accommodate up to 10 electrons.
- Option B: 6. This is incorrect because a d-orbital can accommodate up to 10 electrons.
- Option C: 8. This is incorrect because a d-orbital can accommodate up to 10 electrons.
- Option D: 10. This is the correct answer because a d-orbital can accommodate up to 10 electrons.
