Question

What is the electron configuration for ${\mathrm{Zn}}^{2+}$?

Answer 1

Zinc:

• Zinc is an element having an atomic number $30$ and an atomic symbol $\mathrm{Zn}$.
• Zinc belongs to d-block elements.

Electronic configuration: The arrangement of electrons into the orbitals of an atom using some fundamental principle is called its electronic configuration.

Electronic configuration of Zinc $\left(\mathrm{Zn}\right)$:

• The electronic configuration of Zinc is $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}3{\mathrm{d}}^{10}4{\mathrm{s}}^2$.

Electronic configuration of Zinc ion $\left({\mathrm{Zn}}^{2+}\right)$:

• $\mathrm{Zn}$ loses its two electrons and results in the formation of ${\mathrm{Zn}}^{2+}$ion.
• The electronic configuration of the Zinc ion is $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}3{\mathrm{d}}^{10}$
