Ionic Bond, Covalent Bond, and Hydrogen Bonding Ionic Bond- An atom that has either a positive or negative charge is known as an ION. Ions form when atoms gain or lose electrons. Covalent Bond - Two atoms that are sharing a pair of electrons are connected by a covalent bond. A covalent bond is much stronger than an ionic bond. Hydrogen Bond- When the negatively charge atom is already taking part in a different covalent bond, the interaction between it and the hydrogen atom is called a hydrogen bond. Hydrogen bonding between different parts of a very large molecule hold it in a particular shape. Hydrogen bonds hold the two nucleotide strands of large DNA molecules together, for example.

The electrons in the atom are attracted to the protons in the nucleus by electromagnetic forces. The protons and neutrons, which are called nucleons, are bound together by a short-ranged attractive potential called the residual strong force.

There are molecules all around us in every part of the world. They are held together by one of three types of bonds. Those three bonds are ionic, covalent, and metallic.
