-1 Charge:

· Chlorate: CO3-1

· Chlorite: ClO2-1

· Cyanide: CN-1

· Dihydrogen Phosphate: H2PO4-1

· Ethanoate: CH3COO -1

· Hydroxide: OH-1

· Hydrogen Carbonate: HCO3-1

· Hydrogen Sulfate: HSO4-1

· Hydrogen Sulfite: HSO3-1

· Hypochlorite: ClO-1

· Nitrate: NO3-1

· Nitrite: NO2-1

· Perchlorate: ClO4-1

· Permanganate: MnO4-1

· Thiocyanate: SCN-1

-2 Charge:

· Carbonate: CO3-2

· Chromate: CrO4-2

· Dichromate: Cr2O7-2

· Oxalate: C2O4-2

· Peroxide: O2-2

· Silicate: SiO3-2

· Sulfate: SO4-2

· Sulfite: SO3-2

· Thiosulfate: S2O3-2

-3 Charge:

  • Phosphate: PO4-3
  • Phosphite: PO3-3

There is a helpful phrase for remembering a few polyatomic ions.

consonants represent the number of Oxygens

Vowels represent the amount of extra electrons

NiCK- Nitrate = NO3 (-1 charge)

the

CaMeL- Carbonate CO3 (-2 charge)

ate

CLaM- Chlorate ClO3 (-1 charge)

and

BraN- Bromate BrO3 (-1 charge)

for

SuPPeR- Sulfate SO4 (-2 charge)

in

PHoeNiX- Phosphate PO4 (-3 charge)

*If the ending is -ite instead of -ate, this means the oxygen count goes down 1.

*For every hydrogen in front, the electron count goes down 1 (charge increases)

For example, Hydrogen Carbonite (or Bicarbonite) has the formula HCO2 (-1 charge)

Perchlorate= ClO4 (-1 charge) extra oxygen

Hypochlorite= ClO (-1 charge) loses 2 oxygens from base

Other polyatomic ions include:

Hydroxide- OH (-1 charge)

Ammonium- NH4 (+1 charge)

Acetate- C2H3O2 (-1 charge)

Cynide- CN (-1 charge)

Chromate- CrO4 (-2 charge)

Which of these is an example of a polyatomic cation?

The ammonium ion, NH4+, is the only polyatomic cation.


What is anion cation and polyatomic ion?

Well, a polyatomic may contain a cation in it. A cation is a positively charged ion. They are usually metals. A good way to remember is: "cats" have "paws" because they are "pawsitive". Cheesy, right? Anyways, an example of a polyatomic that contains a cation is NH4+. You know that this polyatomic has a cation by the +1 superscript. This + sign signifies a positive ion, which is called a cation!


Is ammonium an oxyanion?

No. An oxyanion is a polyatomic negative ion that contains oxygen. Ammonium is a cation (positive ion) and does not contain oxygen.

Is NH4NO3 Ammonium Nitrate a molecular or ionic substance?

It's an ionic substance. Well it's true that ionic substances are usually composed of a metal + a non-metal (or a polyatomic anion), but ionic substances can also be composed of a polyatomic cation + a non-metal (or a polyatomic anion). anion: negatively charged ion cation: positively charged ion
