What is the ground-state electron configuration of the element $\mathrm{Kr}$?

Krypton:

• Krypton is a p-block element having the atomic number $36$ and an atomic symbol $\mathrm{Kr}$.
• Krypton is a colourless/odourless gas.
• Krypton belongs to noble gases.

Electronic configuration of Krypton:

• The electronic configuration of Krypton at the ground state is $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}4{\mathrm{s}}^{2}3{\mathrm{d}}^{10}4{\mathrm{p}}^6$.
• Due to the fully filled electronic configuration, Krypton is also known as inert gas because it is very less reactive.
