Eating, putting gas in a car and throwing a log on a campfire all involve adding energy to a system. In each case, the energy is added in the form of covalent bonds that hold atoms together in molecules. Covalent bonds are one of four types of chemical bonds. The other three are ionic bonds, metallic bonds and hydrogen.

Nov 9, 2010. A chemical bond is the energy or force which holds two or more atoms together in a molecule or compound. It is an incredibly commonly used term, and its very important that the basics behind bonds are understood, if reactions from real life are to be understood. Simply understanding how a collection of.

Atomic Bonding. Covalent Bonds. GN Lewis. A covalent bond is an inter atomic linkage between two atoms. The bonded atoms have a lower total energy than that found in widely separated atoms. The sharing of a pair of electrons creates a force of attraction between the atomic centers (positively charged) and the same.
