Question

The ground state electron configuration of $\mathrm{Fe}$ is_______.

Answer 1

Electronic configuration

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

The ground state electron configuration of $\mathrm{Fe}$

• The atomic number of $\mathrm{Fe}$ is $26$.
• The ground-state electron configuration of $\mathrm{Fe}$ is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^6$.

The ground-state electron configuration of $\mathrm{Fe}$ is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^6$.
