Best Answer

Long-hand version:

1s^2 2s^2 2p^6 3s^2 3p^6 4s^1 3d^5

Short-hand version:

[Ar] 4s^2 3d^4

Note: The "^" symbol means the the following number is in the form of a superscript.

The above is wrong because Cr is an exception. the actual answer is [Ar] 4s^1 3d^5 because it has a half filled subshell
