The number of orbitals in a d subshell is
Correct answer: B. 5
- A. 3
- B. 5
- C. 7
- D. 1
Explanation
The number of orbitals in a subshell is 2l plus 1, and for a d subshell l equals 2, giving five orbitals that together hold up to ten electrons. A p subshell has three orbitals and an f subshell seven. Each orbital holds a maximum of two electrons with opposite spins.

About Shapes of Orbitals
Atomic orbitals are three-dimensional regions where an electron is most likely to be found, not fixed circular paths. The content covers the spherical s orbitals, dumbbell-shaped p orbitals, clover-shaped d orbitals, the orientations of orbitals, and how quantum numbers determine their shapes and energy levels.
