What is the ground-state electron configuration of a neutral atom of iodine?

Iodine:

• Iodine is a p-block element having an atomic number $53$ and an atomic symbol $\mathrm{I}$.
• It belongs to the Halogen family i.e. Group-$17$.
• It is a non-metallic solid with a semi-lustrous appearance.

Electronic configuration of Iodine:

• The electronic configuration of a neutral atom of Iodine is $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}4{\mathrm{s}}^{2}3{\mathrm{d}}^{10}4{\mathrm{p}}^{6}5{\mathrm{s}}^{2}4{\mathrm{d}}^{10}5{\mathrm{p}}^5$.
• It can also be written as $\left[\mathrm{Kr}\right]4{\mathrm{d}}^{10}5{\mathrm{s}}^{2}5{\mathrm{p}}^5$
