A metal ion is a type of atom compound that has an electric charge. Such atoms willingly lose electrons in order to build positive ions called cations. Ions are essentially enclosed by delocalized electrons which are responsible for processes like conductivity.

What is ionic metal and nonmetal?

Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. … Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal.

Is NaCl ionic or covalent?

Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons.
