#Ni = 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^8#

#Ni = [Ar] 4s^2 3d^8#

Explanation:

Nickel is in the #4th# energy level, #d# block, #7th# column, this means that the electron configuration will end #3d^8# with the #d# orbital being one level lower than the energy level it is on.

#Ni = 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^8#

#Ni = [Ar] 4s^2 3d^8#
