**An electron in a mercury atom is in the 3 d sub-shell. Which of the following ${{\mathit{m}}}_{{\mathbf{l}}}$ values are possible for it: -3, -1, 0, 1, and 2?**

The possible values for 3*d* the sub-shell of the electron of mercury atom are -1,0,1,2.

An electron in a mercury atom is in the 3*d* sub-shell.

**Using the concept of possible values for the magnetic quantum number that depends on the orbital angular quantum number, we can get the required possible values of the magnetic number. **

** **

**For every l value of a subshell, we have - l to +I possible m values for the same electron.**

We have an electron of mercury atom in 3d subshell; thus, the value of the orbital quantum number is given by:

$I=2\phantom{\rule{0ex}{0ex}}n=3,f\mathrm{or}\mathrm{the}\mathrm{d}\mathrm{subshell}$

Thus, the possible values of ${m}_{l}$ are: -2,-1,0,1,2.

Hence, the possible values considering the question are -1,0,1,2.
