Nickel (Ni) is located in the 4th energy level (row) of the periodic table, column 10 (VIII). This position would be an electron configuration of

#1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^7#

To convert this to the Noble Gas notation we revert back to the Noble Gas from period 3 of the periodic table Argon

Argon - Ar #1s^2 2s^2 2p^6 3s^2 3p^6#

We then replace this section of Nickel's electron configuration with [Ar].

#[Ar] 4s^2 3d^7#

I hope this was helpful.
