Question

What is nickel's electron configuration?

Answer 1

Electronic configuration of d-block

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

Electronic configuration of nickel

• Nickel is a d-block element.
• The symbol for nickel is $\mathrm{Ni}$ and its atomic number is 28.
• The electronic configuration of $\mathrm{Ni}$ is $\left[\text{Ar}\right]3{\mathrm{d}}^{8}4{\mathrm{s}}^2$.
