What quantum number(s) is(are) required to completely describe a subshell , a set of orbitals with the same energy and shape?
I. Principal quantum number
II. Angular Momentum quantum number
III. Magnetic quantum number

Question

Quizplus · Accepted Answer

To completely describe a subshell, both the principal quantum number (I) and the angular momentum quantum number (II) are required. The principal quantum number determines the energy level of the electron, while the angular momentum quantum number defines the shape of the orbital. The magnetic quantum number (III) further divides the subshell into individual orbitals but is not necessary to describe the subshell itself.
