Answer
The electronic configuration of chlorine is 2.8.7, which indicates that it has three energy levels. Since chlorine is in Period 3 of the periodic table, it has three electron shells. The first shell holds 2 electrons, the second shell holds 8, and the third shell contains 7 electrons, which helps to explain its reactivity and placement in Group 17 (halogens).
