[AI-generated answer — Bot GPT 3.5]

To determine the number of atoms in the products, we need to first write out and balance the chemical equation for the reaction:

Br2 + 2KCl -> 2KBr + Cl2

From this balanced equation, we can see that two molecules of potassium bromide (KBr) and one molecule of chlorine gas (Cl2) are produced.

In KBr, there is one bromine atom per molecule, so there are 2 bromine atoms in total (2 x 1 = 2).

In Cl2, there are two chlorine atoms per molecule, so there are also 2 chlorine atoms in total (1 x 2 = 2).

Overall, in the products, there are a total of 2 bromine atoms and 2 chlorine atoms, giving us a total of 4 atoms.
