The correct electron configuration for Mn2+ is [Ar] 3d5.

Here's why:

1. The electron configuration for Mn (Manganese) is [Ar] 4s2 3d5.

2. When Mn loses two electrons to become Mn2+, it loses the 4s electrons first (this is due to the 4s electrons being further from the nucleus and thus easier to remove).

3. So, after losing two electrons, the electron configuration becomes [Ar] 3d5.
