NH4+(aq) The (aq) means 'aqueous' which means that it is in solution - if you're not using state symbols don't put this in.
It is NH4+
The chemical symbol for ammonium is NH4, and it has a valency of 1. Remember ammonium is a radical.
The valency of dichromate ion (Cr₂O₇) in ammonium dichromate (NH₄)₂Cr₂O₇ is 6. This is because the two chromium atoms each have a valency of 6 in the dichromate ion, which is balanced by the two ammonium ions with a valency of 1 each.
The valency of sulfur in ammonium sulfate is 6. This is because each sulfate ion (SO4^2-) contains one sulfur atom with a valency of 6 due to its ability to form 6 covalent bonds by accepting two electrons from each of the four oxygen atoms.
I think the formula of aluminate is AlO2 and valency is 1
Valence is a property of atoms (or of particles acting in similar roles), not of molecules, and ammonium sulphate consists of molecules. So it doesn't have a valency. Please see the link.
In ammonium perchlorate, the valency of nitrogen is +1. This is because nitrogen in the ammonium ion (NH4+) carries a +1 charge.
The chemical symbol for ammonium is NH4, and it has a valency of 1. Remember ammonium is a radical.
The valency of an ammonium ion is 1 (positive).
The valency of dichromate ion (Cr₂O₇) in ammonium dichromate (NH₄)₂Cr₂O₇ is 6. This is because the two chromium atoms each have a valency of 6 in the dichromate ion, which is balanced by the two ammonium ions with a valency of 1 each.
The valency of sulfur in ammonium sulfate is 6. This is because each sulfate ion (SO4^2-) contains one sulfur atom with a valency of 6 due to its ability to form 6 covalent bonds by accepting two electrons from each of the four oxygen atoms.
The valency of Ammonium (NH4) is +1.
I think the formula of aluminate is AlO2 and valency is 1

For example sodium oxalate has the chemical formula Na2C2O4.
Valency of k=1+ valency so4=2- after crisscrossing the valencies, we get- chemical formula- k2so4
The valency of manganese is typically +2 or +3. The chemical formula for the most common compound, manganese oxide, is MnO2.
The valency of hydrogen sulfate is -1. It has the chemical formula HSO4-.
