are ionic compounds usually metals
Cations are usually metals, while anions are usually non-metals, or polyatomic. On the other hand, a covalent compound is usually formed when two non-metals are bonded together. In this type of compound, the electrons are shared (and not transferred), and this causes the bond between them. An ionic bond is formed between a metal and a non-metal. Non-metals(-ve ion) are stronger than the metal(+ve ion) and can get electrons very easily from the metal. These two opposite ions attract each other and form the ionic bond. On the other hand, covalent compounds are non-metals which are bound together, and consist of two electrons that are shared between two atoms. The molecules of an ionic compound are bonded together by the electrical attraction of the two or more ions. Nonmetals and metals generally form: ionic bonds in which they exchange electrons., ionic bonds in which they share electrons., covalent bonds in which they exchange electrons., or covalent bonds in which they share electrons. Metals readily lose electrons to nonmetals to form cations. So ionic compounds almost always contain a metal as the cation and a nonmetal as the anion (except in the case of polyatomic ions). If the compound contains a metal, it's a safe bet that the compound is ionic. On the other hand, covalent compounds are non-metals which are bound together, and consist of two electrons that are shared between two atoms. The molecules of an ionic compound are bonded together by the electrical attraction of the two or more ions. These ions can be of two types ‘“ cation and anion. The value of difference in electronegativity between two atoms in a covalent bond is less than 1.7. Covalent bonds often form between similar atoms, nonmetal to nonmetal or metal to metal. Covalent bonding signals a complete sharing of electrons. Covalent bonds form when two atoms have a very small (nearly insignificant) difference in electronegativity. The value of difference in electronegativity between two atoms in a covalent bond is less than 1.7. Covalent bonds often form between similar atoms, nonmetal to nonmetal or metal to metal. Metals readily lose electrons to nonmetals to form cations. So ionic compounds almost always contain a metal as the cation and a nonmetal as the anion (except in the case of polyatomic ions). On the other hand, a covalent compound is usually formed when two non-metals are bonded together.
