KClKCl

Explanation:

When potassium solid (KK) is mixed with chlorine gas (Cl_2Cl2) the reaction is the following:

2K(s)+Cl_2(g)->2KCl(s)2K(s)+Cl2(g)2KCl(s)

The empirical formula, which is the same as the formula unit would be: KClKCl.

Note that ionic compounds are always written as their empirical formula.
