The ground state electron configurations listed here are incorrect. Identify the mistakes that have been made in each and write the correct electronic configurations.
`Cl, 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6)`

Explanation

To solve the problem of identifying the mistakes in the given ground state electron configuration for chlorine and writing the correct configuration, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Atomic Number of Chlorine**:
Chlorine (Cl) has an atomic number of 17. This means it has 17 electrons in its neutral state.

2. **Understand the Electron Configuration**:
