Answer 2

Answer:

A molecular ion is a covalently bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero. Unlike a molecule, which has a net charge of zero, this chemical species is an ion. .A simple example of a polyatomic ion is the hydroxide ion, which consists of one oxygen atom and one hydrogen atom, jointly carrying a net charge of −1; its chemical formula is OH−

. In contrast, an ammonium ion consists of one nitrogen atom and ‘’four’’ hydrogen atoms, with a charge of +1; its chemical formula is NH+
