Question

What is the electronic configuration of Ni4+

Answer 1

$\textsf{\underline{\Large{Electronic Configuration}}}$ :

$\boxed{ \mathsf{{Ni}^{4+}\:=\:1{s}^{2}\:2{s}^{2}\:2{p}^{6}\:3{s}^{2}\:3{p}^{6}\:\:3{d}^{4}\:4{s}^{2}}}$

$\textsf{\underline {Electronic Configuration of atoms}}$ :

Electronic configuration of atoms is the distribution of electrons in different orbitals.

This is governed by the 3 main principles :

1 ). $\textsf{\underline {Aufbau Principle}}$ : In the ground state, the electrons are filled in order of their increasing energies.

2 ). $\textsf{\underline {Pauli's Exclusion Principle}}$ : An orbital can accommodate maximum number of two electrons with opposite spin.

3 ) $\textsf{\underline {Hund's Rule of Maximum Multiplicity}}$ :

The pairing of electron doesn't take place until each orbital acquires one electron with same spin.
