Which statement is true about the formation of bonds? a. there is an overall release of energy when bonds form. b. there is an overall energy increase when bonds form. c. a bond is formed as atoms are split apart from each other. d. bonds are always first-order.

A. 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.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
