I remember learning in high school that breaking bonds actually takes energy and forming bonds releases energy but I can't remember why. Can anyone explain/ did we ever go over it?

Forming bonds releases energy because when bonds are formed, octets are filled, and it puts atoms at a lower energy state.

Because bonds are attractions between atoms, it takes energy to break them, because their tendency is to want to stay together.

In addition to this, when a bond is broken I believe the electron is going to a higher energy state, and this requires energy
