Ionic compounds do not form between nonmetallic elements. Nonmetallic elements form covalent bonds, and form molecular compounds. Ionic compounds are generally formed by metals and nonmetals.
silicone
A compound
The substance formed by the chemical combination of two or more elements is a compound.
When a metallic atom and a nonmetallic atom have an electron transfer to form an ion, this is known as an ionic compound. For example, salt (NaCl) an electron transfer occurs. The Na, which has 1 electron on its valence shell ( outer shell) and the Cl, which has 7 electrons on its valence shell. The Na transfers its one electron to the Cl. This therefore results in the Cl having a full valence shell; at this point Cl is negative and Na is positive. We can then conclude the NaCl is an ionic compound.
