Question

What is the electronic configuration of Nickel?

Answer 1

Nickel:

• Nickel is a d-block element having atomic number 28.
• The chemical symbol of Nickel is ‘Ni’

Electronic configuration of d-block

• In general, the electronic configuration of these elements is $(\mathrm{n}-1){\mathrm{d}}^{1-10}{\mathrm{ns}}^{1-2}$.
• Here, (n–1) stands for the inner $d$orbitals which may have one to ten electrons, and the outermost $\mathrm{n}s$ orbital may have one or two electrons.

Electronic configuration of Nickel:

• The electronic configuration of Nickel should be $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}4{\mathrm{s}}^{2}3{\mathrm{d}}^8$
• It can be written as $\left[\mathrm{Ar}\right]4{\mathrm{s}}^{2}3{\mathrm{d}}^8$
