Which chemical species can form an ionic bond with an anion? Hg22+ NO2– SO32– Ar

Which chemical species can form an ionic bond with an anion? Hg22+ NO2– SO32– Ar Anion has a negative charge,  so will be a non metallic element. an ionic bond is formed between metal and non mental, therefore Hg2+ being both metallic and having a positive charge, is the cation required to form an ionic
