Answer 1

The electron configuration for the Co3+ ion is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁴.

Step-by-step explanation:

The electron configuration for the Co3+ ion can be determined by looking at the electron configuration of the neutral cobalt atom (Co). The electron configuration for cobalt is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁷. To form Co3+ ion, three electrons are removed from the 3d subshell. Therefore, the electron configuration for the Co3+ ion is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁴.
