Answer 2

The electronic configuration of $Ni$  is $1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 3d^{8} 4s^{2}$ .

Explanation:

• Electronic configuration - the representation of the $e^{-}$ distribution in an atom.
• The filling or orbitals takes place according to Aufbau's principle. The order is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s²......
• The filling of electron also follows Hund's rule, that is the orbitals will first be singly filled and then pairing of electrons take place

• The atomic number of nickel is 28 so its electronic configuration will be 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁸ 4s².
• It is also represented as [Ar] 3d⁸ 4s².
