The ground-state electron configuration of neutral calcium (Ca) is \(1s^2 2s^2 2p^6 3s^2\).
When calcium loses two electrons to become Ca²⁺, the electrons are removed first from the outermost shell, which in this case are the two 3s electrons.
Therefore, the electron configuration for Ca²⁺ is:
\[ 1s^2 2s^2 2p^6 \]
If you want it in a single line without formatting:
1s2 2s2 2p6
