It has 3 unpaired electron .
Thnx

Answer 2

Answer:

Chromium ion (Cr3+) has three unpaired electrons.

Step-by-step explanation:

• Atomic number of Cr is 24. So, the electronic configuration of Cr is:

        $[Ar]3d^{5} 4s^{1}$

• The electronic configuration of Cr3+ is:

        $[Ar]3d^{3}$

• Unpaired electrons refer to the number of electrons in the outer most shell.
• Three unpaired electrons are present in the 3d subshell.

Hence, the number of unpaired electrons in Cr3+ is three.
