The electron configuration of a chlorine atom is:

1. Identify the atomic number of chlorine. The atomic number of chlorine is 17, which means it has 17 electrons in a neutral atom.

2. Start filling the energy levels with electrons. According to the Aufbau principle, electrons fill the lowest energy levels first.

3. The first energy level (1s) can hold up to 2 electrons. So, we put 2 electrons in the 1s orbital. Now we have 15 electrons left.

4. The second energy level can hold up to 8 electrons (2 in the 2s orbital and 6 in the 2p orbital). So, we put 2 electrons in the 2s orbital and 6 electrons in the 2p orbital. Now we have 7 electrons left.

5. The third energy level can also hold up to 8 electrons (2 in the 3s orbital and 6 in the 3p orbital). We put 2 electrons in the 3s orbital and 5 electrons in the 3p orbital. Now we have 0 electrons left.

6. Therefore, the full electron configuration of the chlorine atom is 1s² 2s² 2p⁶ 3s² 3p⁵.
