Bond energy definition chemistry gcse
WebSimple molecules contain only a few atoms. held together by covalent bonds. An example is carbon dioxide (CO 2 ), the molecules of which contain one atom of carbon bonded with two atoms of oxygen. WebBond energy is the measure of a bond’s strength; the bigger the bond energy, the stronger the chemical bond. If the bond energy of a chemical bond is negative, the bond cannot exist because it will be too unstable. Therefore, it is almost impossible for a chemical bond to have a negative value for its bond energy.
