For example, sodium atom on donating an electron to chlorine atom forms an ionic bond due to transfer of electron.

This formation of ionic bond leads to the formation of a new compound named as sodium chloride.

Therefore, we can conclude that the statement a chemical change involves the formation or the breaking of bonds, is true.
