Question

What is the electron configuration of Potassium?

Answer 1

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

Electronic configuration of Potassium(K):

• Potassium is an alkali metal having atomic number 19.
• So, the electronic configuration Potassium is $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}4{\mathrm{s}}^1$.

• It can also be written as $\left[\mathrm{Ar}\right]4{\mathrm{s}}^1$.
