Step-by-step explanation:
Usually, metallic bonding is present in metallic elements (E.g Mg). Metallic bonding is described as the attracrion between positive ions and the sea of delocalised electrons.
covalent bonding are usually found in compounds containing only non-metal elements (E.g H20, CO2). Covalent bonding is formed by sharing of electrons.
Ionic bonding is found in compounds containing both metals and non metal elements. (E.g ZnOH2). It is the electrostatic force of attraction between positive and negative charges. Salts are usually ionic compounds.
