The allowed values of magnetic quantum nunber `(m_(l))` are the integers from

Options

A. `.-lto +(l-1)`
B. `-(l - 1)`to +l`
C. `-l` to +l`
D. s

Answer

C

Explanation

Within a subshell, the value of `m_(i)` depends on the values of the angular momenutm quantum number `l`. For acertain value of `l`, there are `(2l +1)` intergral values of `m_(l)` as follows: `-l, (-l +1),..,0,….(+l+1), +l`. For `l = 0 (s` subshell), the allowed `m_(l)` quantum number is `0` only, there is only one orbital in the `s` subshell. For `l = 1 (p` subshell), `m_(l) =- 1, 0`, and `+l`, there are three different orbitals in the `p subshell. these orbitals have the same enegry and identical shape but different orientations in space.
