Ionic bonds. Ionic bonds are electrostatic interactions formed between ions of opposite charges. For instance, most of us know that in sodium chloride (NaCl) positively charged sodium ions and negatively charged chloride ions associate via electrostatic (+ attracts -) interactions to make crystals of sodium chloride, or table salt, creating a crystalline molecule with zero net charge.

GCSE/IGCSE science-Chemistry Quiz Questions on Chemical Bonding, Structure and Properties of ionic, covalent and metallic substances (easier/foundation tier/level)
Ionic compounds are between metals and nonmetals or between metals and polyatomic ions. Examples are sodium chloride (NaCl), magnesium nitrate [Mg(NO 3 ) 2 ] and ammonium sulfate [(NH 4 ) 2 SO 4 ]. When an ionic substance is dissolved in aqueous solution, it ALWAYS ionizes and the ions always have a charge.

Ionic Bonds – Weak or Strong? (thanks for asking!) This "discussion" stemmed from a question asked by a student who was taking organic and cell bio at the same time. In cell bio, the student was told that ionic bonds are very weak. But in organic lecture, the student was told that a strong Li-O ionic bond helped drive a particular reaction.

Metal and nonmetal elements form ionic bonds when they combine to form compounds. The ionic bond involves a transfer of electrons. The metal atom loses one or more electrons to form a positive ion (cation). The nonmetal atom gains one or more electrons to form a negative ion (anion).
1. Molecular compounds are pure substances formed when atoms are linked together by sharing of electrons while ionic compounds are formed due to the transfer of electrons. 2. Molecular compounds are made due to covalent bonding while ionic compounds are made due to ionic bonding. 3.
