Answer 1

Answer:

NH₄⁺

H₂PO₄⁻

H₃O⁺

Explanation:

• An ion is an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

• Ion may be positively charged "cation" or negatively charged "anion".

• Neutral molecule has a net charge of zero.

So, the species that are ions are:

NH₄⁺

H₂PO₄⁻

H₃O⁺
