Covalent bonding is an important and extensive concept in chemistry, and it will be treated in considerable detail in a later chapter of this text. This cookie is set by GDPR Cookie Consent plugin. Whereas ionic compounds are usually formed when a metal and a nonmetal combine, covalent compounds are usually formed by a combination of nonmetals. Similarly, nonmetals (especially those in groups VIA and VIIA, and, to a lesser extent, those in Group VA) can gain the number of electrons needed to provide atoms with the same number of electrons as in the next noble gas in the periodic table.
