Which Periodic Table Groups Form Soluble Anion and Cation Salts?

[extraordinarygirl]

Which group in the periodic table will most likely form anions with salts that are usually soluble? Which group in the periodic table will most likely form cations with salts from the periodic table?

I am thinking that the anions would be the alkali metals (group 1) but I don't know what the cations would be...?

Think of which elements do the least work to get to an octet. Alkali metals lose 1 electron; which column gains 1 electron? Halogens.
Cations are positive and anions are negative. Sodium is a cation, chloride is an anion.
