General atomic group symbol

In many chemical reactions, this atomic group participating as a whole is called atomic group.

Carbonate: CO3-2 valence

Sulfate: SO4-2 valence

Hydroxide: OH- 1 valence

Nitrate: NO3- 1 valence

Ammonium: NH4+ 1 valence

Bicarbonate: HCO3- 1 valence

Phosphate: PO4-3 valence

Nitrite: NO2- 1 valence

Sulfite: SO3-2 valence

Chlorate: ClO3- 1

Hypochlorite: ClO- 1 valence

Permanganate: MnO4- 1 valence

Manganese radical: MnO4-2 valence

These two roots look very similar, but the valence of manganese is different. Manganese in permanganate is +7, and manganese in manganate is +6.

Cyanide: CN- 1 valence

Thiocyanate: SCN- 1 valence

Hydrogen phosphate: HPO4-2 valence

Dihydrogen phosphate: H2PO4- 1 valence
