The main difference between Anion and Bromite is that the Anion is a atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom a net positive or negative electrical charge and Bromite is a chemical compound.
An ion () is an atom or molecule that has a non-zero net electrical charge (its total number of electrons is not equal to its total number of protons). A cation is a positively-charged ion, while an anion is negatively charged. Because of their opposite electric charges, cations and anions attract each other and readily form ionic compounds.
Ions consisting of only a single atom are termed atomic or monatomic ions, while two or more atoms form molecular ions or polyatomic ions. In the case of physical ionization in a medium, such as a gas, “ion pairs” are created by ion collisions, where each generated pair consists of a free electron and a positive ion. Ions are also created by chemical interactions, such as the dissolution of a salts in liquids, or by other means, such as passing a direct current through a conducting solution, dissolving an anode via ionization.
Bromous acid is the inorganic compound with the formula of HBrO2. It is an unstable compound, although salts of its conjugate base – bromites – have been isolated. In acidic solution, bromites decompose to bromine.
A negatively charged ion.
