Zinc atomic wt=65.38
Chlorine atomic wt=35.453
okay, what combination of those weights will give us exactly 136.28
two zincs would clearly be too much (wouldn't leave room for even one chlorine) so we know there is one zinc
136.28-65.38= 70.90 (amount of zinc chloride that must be chlorine)
70.90 looks like 2 zincs (since they are 35.45 each)
ZnCl2
voila!

Zinc is a cation which has a charge of +2 while chlorine, when an ion is chloride which has a charge of -1, specifically an anion.
For it to be compatible with each other, when asked the sum of both charges, it becomes zero. Since +2 and -1 is +1, you have to criss cross it on order to get zero, whatever the charge of the cation becomes the subsrcipt of the anion and whatever the charger of the anion becomes the charge of the cation, therefore the answer is ZnCl2
