The number of orbitals in the 2p and 3d subshells are, respectively:

A2 and 3
B6 and 10
C3 and 5
D3 and 10
Answer & Solution
Correct answer: C. 3 and 5
1. The number of orbitals in a subshell follows from the magnetic quantum number. 2. A p subshell has three orientations, so 2p holds 3 orbitals. 3. A d subshell has five orientations, so 3d holds 5 orbitals. 4. Each orbital takes at most two electrons, so 2p holds 6 electrons and 3d holds 10. 5. Answering 6 and 10 confuses the electron capacity with the orbital count, which was the recorded error. _Source: NECTA ACSEE 2023 Chemistry 132/1, Question 4: The Atom_
