Chemical Bonds

When atoms approach each other, their nuclei repel each other, as do the electrons. Concurrently, the electrons from each atom are attracted to each other's nucleus and arrange in such a way to maximize the attractive forces between the atoms while minimizing the repulsive forces.

If this results in a net attractive force, the potential energy of the system is lowered. This interaction is called a chemical bond.

However, not every combination of atoms can form stable chemical bonds. An atom’s chemical behavior is primarily determined by what forms bonds and what type of bonds they are. Understanding the bonding between atoms that make a compound helps to comprehend and predict their molecular behavior.

Bond energy is the energy required to break a bond in one mole of a gaseous compound. It depends on the type of bonded atoms and the number of electrons involved. Bond strength increases with bond energy.

The type of bonded atoms and number of electrons involved also influence the bond length, which is the average distance between the nuclei of two bonded atoms and is inversely proportional to the bond multiplicity and bond strength.

The most common bonding interactions fall on a spe
