No, a base is a substance that raises pH when added to water. While some bases do indeed release metal and nonmetal ions, many do not, and many that release metal/nonmetal ions are not bases.
SO2 is not a metal; it is a nonmetal compound.
Silver nitrate is a compound that is composed of a metal (silver) and nonmetal (nitrate) elements. Silver is a metal because it is a good conductor of electricity, whereas nitrate is a nonmetal as it typically forms negative ions in chemical reactions.
A binary ionic compound is formed between two elements, typically a metal cation and a nonmetal anion. For example, sodium chloride (NaCl) is a type of binary ionic compound where sodium (metal) forms a cation and chlorine (nonmetal) forms an anion.
Ionic compounds generally result when nonmetal atoms chemically combine with metal atoms. This occurs through the transfer of electrons from the metal to the nonmetal, creating positively charged metal cations and negatively charged nonmetal anions that are held together by electrostatic forces.
FeO is not a nonmetal; it is a compound composed of iron (a metal) and oxygen (a nonmetal).
This is typical behavior of soluble salts: metal cations (+) and nonmetal anions (-)
it forms an ionic compound
When oxygen is bonded to a metal, it forms an oxide compound. When oxygen is bonded to a nonmetal, it forms an oxide compound as well. Oxygen can form both ionic and covalent bonds with different elements depending on their electronegativity.

Lithium chloride (LiCl) is a compound composed of lithium, a metal, and chlorine, a nonmetal. In this compound, lithium acts as the metal, while chlorine is the nonmetal. Therefore, LiCl itself cannot be classified as strictly a metal or nonmetal; instead, it is an ionic compound formed from both types of elements.
Sodium oxide is a compound made up of the metal sodium and the nonmetal oxygen. Sodium is a metal, while oxygen is a nonmetal.
A metal and a nonmetal; but exceptions exist.
