Which is an example of a polyatomic ion? H₂ CO₃^- Mg⁺ Ne⁺

Elements in the same group of the periodic table often form oxyanions with the same general formula. The anions are also named in a similar fashion. Based on these observations, suggest a chemical formula or name, as appropriate, for each of the following ions: (a) BrO₄^- (b) SeO₃^2- (c) arsenate ion

Name the anion obtained by removing one oxygen atom from the perbromate ion, BrO₄⁻.

An atom or a molecule with either a positive or negative charge is referred to as a(n)

Give the chemical formula for d. perchlorate ion

Give the chemical formula for e. hypochlorite ion.
