Question

The electronic configuration of ${\mathrm{Mn}}^{2+}$ is

Answer 1

Electronic configuration

• The distribution of electrons into orbitals of an atom is called its electronic configuration.

Electronic configuration of ${\mathrm{Mn}}^{2+}$

• The atomic number for $\mathrm{Mn}$ is $25$ and the name of the element is Manganese.
• The electronic configuration of $\mathrm{Mn}$ is $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}3{\mathrm{d}}^{5}4{\mathrm{s}}^2$.
• When $\mathrm{Mn}$ loses two electrons, then ${\mathrm{Mn}}^{2+}$ion is formed.
• So, the electronic configuration of ${\mathrm{Mn}}^{2+}$ is $\mathbf{1}{\mathbf{s}}^{\mathbf{2}}\mathbf{2}{\mathbf{s}}^{\mathbf{2}}\mathbf{2}{\mathbf{p}}^{\mathbf{6}}\mathbf{3}{\mathbf{s}}^{\mathbf{2}}\mathbf{3}{\mathbf{p}}^{\mathbf{6}}\mathbf{3}{\mathbf{d}}^{\mathbf{5}}$.
