2K + Cl2-----2KCl
You need to know that Chlorine gas exists as Cl2 so from there the rest follows.

2K+Cl(2)----->2KCl
This equation should be balanced. K (potasium) would have a +1 charge, since it is in the first row of the periodic table. It would have 1 electron in its outer valence, that it would want to give away. Cl (clorine) is in the last row before the noble gases. In its outer valance, it would be short one electron, and would be happy to get it from K. Since Clorine is a gas, it has 2 atoms. It would now have a charge of -1. To balance out the 2 atoms of Cl per molecule of Clorine, you need twice as much K.
The two elements would get together, and form an ionic compound.
BTW, would would have a salt. Not tablesalt, but, still, a salt.

it looks balanced to me.
the potassium has one election, and the chlorine has room for one electron.
