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

Electronic configuration of Nickel ( $""_28"Ni"$ ) is

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

After removal of two electrons from outermost shell the electron configuration of $"Ni"^(2+)$ is

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

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