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 identify the mistakes in the given electron configuration for chlorine (Cl) and write the correct electronic configuration, we can follow these steps:

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

### Step 2: Write the Electron Configuration
The electron configuration is built according to the Aufbau principle, which states that electrons fill orbitals starting from the lowest energy level to the highest.
