Answer
Chlorine has an electronic configuration of 2.8.7, indicating it has 3 energy levels (or shells). This corresponds to Period 3 in the periodic table, as the number of energy levels increases with the period. The '7' in the outermost shell indicates that chlorine is in Group 17, as it has seven valence electrons.
