Answer

### The invalid electron configurations are:1. : This configuration is invalid because the 4d orbital should not be filled before the 4p orbital. The correct configuration is , corresponding to Bromine (Br).2. : This configuration is invalid because the 3d orbital should not be filled before the 3p orbital. The correct configuration is , corresponding to Manganese (Mn).3. : This configuration is invalid because the 3s orbital should not be filled before the 2p orbital is fully filled. The correct configuration is , corresponding to Oxygen (O).4. : This configuration is invalid because already includes . The correct configuration should be , corresponding to Neon (Ne).

Explanation

## Step1: Identify the invalid electron configurations### Review each given electron configuration to check for adherence to the Aufbau principle, Hund's rule, and the Pauli exclusion principle.## Step2: Correct the invalid electron configurations### Rectify the configurations that do not follow the rules, ensuring the correct order of filling orbitals.## Step3: Identify the correct elements### Determine the element corresponding to each corrected electron configuration.
