You have two answers. For this one I would use the method where you find the closest gas, since 28 is a long one.

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

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

Explanation:

This is a concept that takes a while to explain without a periodic table, so I am going to attach this link to a video that explains it pretty well.
