What is the electron configuration for nickel, whose atomic number is 28? Chemistry Electron Configuration Electron Configuration 1 Answer BRIAN M. Jul 2, 2016 #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# Answer link Related questions How do electron configurations in the same group compare?
