Is oxalate a cation or anion?
When you know the acid name, you can derive the anion name from it using these simple rules. In your case, oxalic acid (H2C2O4) contains oxalate ion (C2O42-). Name the compounds. Ionic compounds are named by following the cation name with the anion name.
What is the charge of each hydrogen ion?
+1
A hydrogen ion is formed when a hydrogen atom loses an electron and therefore becomes positively charged (it has a charge of +1). A hydrogen atom is therefore often referred to as just a proton, as it is left with only one proton and no electrons, as a H atom only has one of each.
What ion is Ag+?
Silver ion
Silver ion | Ag+ – PubChem.
What is the formula and charge of the polyatomic ion chlorite?
The chlorite ion, ClO2–, contains 19 (7 from the Cl and 6 from each of the two O atoms) +1 = 20 electrons. One electron is added because the entire molecule has a -1 charge. Hypochlorite ion Lewis structureThe hypochlorite ion, ClO−, contains 13 + 1 = 14 electrons.

How to calculate the charge of a cation?
To do this multiply the charge of the anion by the number of anions divide this by the number of cations. This will give the charge for the cation. Examples: Binary Molecular Formulas – Molecules are compounds that use covalent bonds to join two atoms together. Binary molecules will only have two elements in their formula.
What are the names of the cations and anions?
Common Cations and Anions Name Formula Charge Name Formula Charge Name Formula Charge aluminum Al 3+ +3 magnesium Mg 2+ +2 carbonate CO 3 2– –2 ammonium NH 4 + +1 manganese (II) Mn 2+ +2 chlorate ClO
How are cations and anions arranged in a polyatomic compound?
Most of the polyatomic ions are anions. The formula for the compound will contain both a cation and an anion to balance the overall charge of the compound. The cation is named normally and the anion is given the name of the actual anion.
