What pairs of elements would most likely form a salt?

Salts are typically formed by the reaction of an acid with a base, which usually involves a metal and a non-metal. Common pairs of elements that would likely form a salt include alkali metals (like sodium or potassium) with halogens (like chlorine or bromine), resulting in compounds such as sodium chloride (table salt) or potassium bromide. Additionally, transition metals can also form salts with non-metals, such as copper with sulfur to create copper(II) sulfide.
