Iron reacts with both chlorine and bromine.

The reaction between chlorine and iron is much more vigorous than the reaction between bromine and iron.

Figure 1 shows the electronic configurations of chlorine and bromine atoms.

Figure 1: Schematic diagram of a chlorine atom containing 17 protons with three electron shells populated with 2, 8, and 7 electrons, and a bromine atom containing 35 protons with four electron shells populated with 2, 8, 18, and 7 electrons.

Explain, in terms of their electronic configurations, why chlorine reacts with iron more vigorously than bromine reacts with iron.
