Bond Energy

Definition

Bond energy is the amount of energy required to break a chemical bond and form neutral isolated atoms.

Analogy

Think of bond energy like the cost of breaking up a band. The stronger the bond between band members (atoms), the more effort (energy) it will take to separate them.

Related terms

Activation Energy: This is the minimum amount of energy that reactants must have in order for a chemical reaction to occur.

Endothermic Reaction: A type of reaction where heat is absorbed from surroundings, similar to how breaking bonds requires an input of energy.

Exothermic Reaction: A type of reaction where heat is released into surroundings, akin to how forming bonds releases energy.
