Perchlorate, being an ionic compound, does not have a chemical symbol, per say. The chemical notation is ClO4-, if that is what you were asking.
The atomic symbol for magnesium is Mg. There is no specific atomic symbol for magnesium perchlorate as it is a compound, not an individual element. Magnesium perchlorate is represented by the chemical formula Mg(ClO4)2.
Formula: ClO4-
Formula = NH4ClO4
PbO
Pb2(oh)
PbSO4
ClO4- Note that this is not an "element" and hence doesn't have an "element symbol."
