One reason is that the composition of a polyatomic ion is fixed, just as that of a compound is fixed. If more than one polyatomic ion is present in an ionic compound, the use of parentheses allows a subscript to be used after the right parenthesis to designate the number of ions just as such subscript is used to designate the number of atoms in a compound.
More than one polyatomic ion should be indicated in a chemical formula by putting parentheses around the atoms in the ions and then adding a subscript.
Put parentheses around the atoms in the ion and then add a subscript.
Yes. PO4(3-) Phosphate, for example.
Mg3(PO4)2
Why should be apparent. Mg2PO42 would be very confusing.
Sometimes the last element in Polyatomic ions has a subtext number. So to keep the formula clean parenthesis are used.
put parentheses around the atoms in the ion and then add a subscript - apex
The chemical formula for acetic acid is CH3COOH. It should be noted that acetic acid is the same as ethanoic acid.
The chemical formula for the oxygen in the air is O2, where the 2 should be a subscript.
If this compound exist, the chemical formula should be Pb(BrO4)2.
By definition, a compound is always neutral. If the polyatomic chemical entity has a charge, it is no longer a compound, but is now a polyatomic ion. Ionic compounds and molecular compounds are also neutral in charge. The word "ionic" is just referring to the type of chemical bond in the molecule.

The chemical formula for arcylamide is censored by the government since acrylamid is a dangerous substance. You should not try to find it because it is illegal.
The formula of iron(III) oxalate is C6Fe2O12.
You should try to study these formulas because they are not to difficult. Aluminum is a metal. So... you should first know that it is an ionic bond. Ionic bonds do not have prefixes, so you don't have to worry about adding them. Phosphate is a polyatomic ion. That means it has it's own "special formula." (Which you should study!) So. . . It should look like this ----------> Al PO4 Btw the 4 is below the O, not beside it.
CaS is the chemical formula for calcium sulphide. NB The elemental letters should NOT be separated by spaces. 'Ca S' is incorrect. I should be written as ' CaS'.
