A van der Waals bond occurs due to the attraction of charge-polarized molecules and is considerably weaker than ionic or covalent bonds. The difference between ionic and molecular compounds is that ionic compounds are composed of positive and negative ions held together by ionic bonds.

A covalent bond occurs when two or more atoms share electrons. An ionic bond forms when an electron transfers from one atom to another. Most atoms join by covalent bonding, in which shared electrons form directional bonds. The bond is understood in simple terms as due to an. Ionic compounds are pure substances formed from chemically bonded ions. Trending Questions Is the statement true that unlike planets a dwarf planet cannot have moons?

Ionic bonding refers to a class of chemical bonding between ions found in some substances (i.e., salts).
