The polyatomic ion SO5 does not exist. The closest polyatomic ion to this is SO4^2- which is called sulfate ion.
The polyatomic ion represented by the formula NO2- is the nitrite ion.
NO3-.
A polyatomic ion. For example, ammonium, chemical formula (NH4) with a 1+ electrical overall charge.
When KOH is placed in water, it ionizes to K+ and OH-, so the polyatomic ion is the OH- (hydroxyl anion).
The three most common such ions probably are sulfate, with the formula SO4-2, chromate, with the formula CrO4-1, and perchlorate, with the formula ClO4-1.
The polyatomic ion is a carbonate ion, with formula CO3-2.
The polyatomic ion is a carbonate ion, with formula CO3-2.
The polyatomic ion is the ammonium ion, NH4^+
The polyatomic ion represented by the formula NO2- is the nitrite ion.
The correct formula for the polyatomic ion ammonium is NH4+.
The correct formula for the hypochlorite polyatomic ion is ClO-.
The chemical formula of the polyatomic ion nitrite is NO2-.
The polyatomic ion formula for carbonate is CO3^2-.
HCO3- is the polyatomic ion with which sodium bonds. It is the bicarbonate ion.
Nitrite Ion
Sulfite ion
