# What is the electron configuration of Ni^(2+)?

Jun 10, 2018

${\text{1s"^2\ "2s"^2\ "2p"^6\ "3s"^2\ "3p"^6\ "4s"^0\ "3d}}^{8}$

#### Explanation:

Electronic configuration of Nickel ($\text{_28"Ni}$) is

${\text{1s"^2\ "2s"^2\ "2p"^6\ "3s"^2\ "3p"^6\ "4s"^2\ "3d}}^{8}$

After removal of two electrons from outermost shell the electron configuration of ${\text{Ni}}^{2 +}$ is

${\text{1s"^2\ "2s"^2\ "2p"^6\ "3s"^2\ "3p"^6\ "4s"^0\ "3d}}^{8}$
