Correct answer: 0

Write the electronic configuration of Zn

Zinc has atomic number $30$ .

Its ground-state electronic configuration is:

Zn : [Ar] \, 3d^{10}4s^2

Find the configuration of $Zn^+$

When one electron is removed to form $Zn^+$ , it is removed from the outermost shell first, i.e. from the $4s$ orbital.

So,

Zn^+ : [Ar] \, 3d^{10}4s^1

Identify the outermost electron

The outermost electron is the electron in the $4s$ orbital.

For an $s$ -orbital:

azimuthal quantum number $l = 0$
magnetic quantum number $m_l = 0$

Thus, for the outermost electron of $Zn^+$ ,

m_l = 0

Final answer

The value of magnetic quantum number of the outermost electron of $Zn^+$ ion is:

\boxed{0}

Comparison with stored correct answer

Stored correct answer = $0$

Our derived answer also = $0$ . Hence, they agree.
