I have aluminum and chlorine to form a compound.Aluminum loses 3 electronsDoes the chlorine gain 3 or just 1?
Both atoms in the compound must gain the octet and become stable fo it to become a compoundFor Aluminum to react Chloride there must be 3 chloride atoms for every Aluminum atomBecause Aluminum has a valency of 3, so it needs 3 electrons to fill its outer shellAnd Chloride needs one electron to fill its outer shellSo To make Aluminum Chloride there must be 1 Aluminum and 3 Chloride atoms per molecule.
