I'm almost certain it's a positive charge. I can't remember if it gains or gives electrodes. If it gives electrodes it's positive, if it gains electrodes it's negative Hope this helps :)
It really doesn't, please don't try to help if you're "almost certain" especially since you are wrong about pretty much everything in that statement. Chloride ion is Cl^- meaning it has a negative charge or it receives electrons. Also remember that it's ELECTRONS not electrodes.
A chlorine ion will have a charge of -1. A chlorine atom gains one electron to form the more stable chloride ion, thereby incurring a charge of -1. There is now one more electron than proton in the chloride ion, as compared to the chlorine atom which is electrically neutral.
Chloride ions have a charge of 1-. Since the charge on an Mg ion is 2+, the formula unit of Magnesium Chloride is MgCl2. There are 2 chloride ions for each Mg ion.

calcium becomes the main ion and chloride the secondary ion
It becomes a negative ion.
The chloride ion carries a -1 charge.
It becomes a chloride ion with a 1- charge.
-1.
It becomes a chloride ion with a 1- charge.

When it gains an electron. It then becomes a negative ion.
Chloride ion in AlCl3 has a charge of -1. The compound AlCl3 is aluminum chloride, which is an inorganic compound that can react with water.
