What is true about the formation of a bond?
timama [110]

Answer:

There is an overall release of energy when bonds form.

Explanation:

There is a general release of energy when bonds form. This energy is called bond energy.

Bond energy is involved in the breakdown or formation of one or more bonds between atoms of a molecule. Atoms bond with each other to achieve their electronic stability, that is, they move from a higher energy situation to a lower energy one. With this we can state that when the bond between atoms is formed, energy is released; therefore, its breakdown depends on energy absorption.
