IT is a negatively charged ion consisting of more than one atom
The PO4^3- ion is a polyatomic anion. It consists of a group of atoms with an overall negative charge.
When KOH is placed in water, it ionizes to K+ and OH-, so the polyatomic ion is the OH- (hydroxyl anion).
The anion (HCO3) has the electrical charge -1.
The two components of a salt are a positively charged ion (cation) and a negatively charged ion (anion). The cation is usually a metal or a positively charged polyatomic ion, while the anion is usually a nonmetal or a negatively charged polyatomic ion.
When using the criss cross method with a polyatomic ion, simply treat the polyatomic ion as a single unit. Cross the charges of the cation and anion to determine the subscript of the other ion. Ensure to simplify the ratio by reducing to the lowest whole numbers.
The PO4^3- ion is a polyatomic anion. It consists of a group of atoms with an overall negative charge.
polyatomic anion
A polyatomic anion is a tightly bound group of atoms that behaves as a unit and has a negative charge.A monatomic anion consists of a single atom with a negative charge.
This is a polyatomic anion.
An example of this type of compound is ammonium sulfate (NH4)2SO4, where the polyatomic cation is ammonium (NH4+) and the polyatomic anion is sulfate (SO4^2-). In this case, the atoms in the sulfate anion are all from the same group in the periodic table (Group 16 or the oxygen family).
Chromate is an divalent anion with formula CrO4-2
The chemical name for an ionic compound with a polyatomic cation and polyatomic anion would typically be named using the names of the individual ions. The cation would be named first followed by the anion, with the ending of the anion typically changed to "-ide," similar to naming binary ionic compounds.
Phosphate is a triply charged polyatomic anion.
Hydronium is a polyatomic cation.
CaSO4 is a polyatomic ionic compound. It consists of a metal cation (Ca2+) and a polyatomic anion (SO42-) that are attracted to each other through ionic bonds.
When KOH is placed in water, it ionizes to K+ and OH-, so the polyatomic ion is the OH- (hydroxyl anion).
The anion with the formula NO3-1 is a covalently bonded polyatomic ion.
