Which one of the following explain the shape of orbitals _________________?
Correct answer: B. Azimuthal quantum number
- A. Principal of quantum number
- B. Azimuthal quantum number
- C. Magnetic quantum number
- D. Spin quantum number
Explanation
The azimuthal quantum number, l, determines the subshell and therefore the shape of an orbital: s is spherical, p is dumbbell-shaped, and so on. The magnetic quantum number determines orientation, not the basic shape. Students may choose the principal quantum number because it specifies the main shell and energy level.

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.
