The perchlorate ion has one available bond.
Symbol: Cl-Valency: -1.
+1
You don't say that. What you do say is that the valency of sulphur in sulphur trioxide is 6.
Okay, a mole of potassium perchlorate contains 6.02x1023 formula units of potassium perchlorate, but you're asking about individual atoms. So, let's look at the formula: KClO3. That's 1 potassium, 1 chlorine, and 3 oxygens, for a total of 5 atoms per formula unit. Now, multiple 5 by Avogadro's number above, to get 30.1x1023, which simplifies to 3.01x1024 atoms.
The common valences of cobalt are +2 and +3.
In ammonium perchlorate, the valency of nitrogen is +1. This is because nitrogen in the ammonium ion (NH4+) carries a +1 charge.
The answer is Cd(ClO4)2 The charge of cadmium(II) is 2+, and the charge of ClO4 is 1-. So to even the charges we must have two of the ClO4.
The general formula of a perchlorate is MeClO4, where Me is a metal. The anion perchlorate is monovalent.
Aluminium perchlorate is not renewable.
The silver ion is Ag+ and the perchlorate ion is ClO4-, so silver perchlorate would have the formula of AgClO4.
The chemical symbol for perchlorate is ClO4-.
ammonium perchlorate
The compound with the name AgClO4 is silver perchlorate. It is composed of silver (Ag) and perchlorate (ClO4-) ions.
ferrous perchlorate
The valency of lithium is 1. It has one valence electron in its outer shell.
Perchloric Acid
The chemical formula for ammonium perchlorate is NH4ClO4.
