Does it take energy to make or break bonds? [Expert Review!]

WebThe amount of energy required to break a bond is the same as the amount of energy released when it forms. Most chemical reactions involve both the breaking and making of chemical bonds. If the energy released by forming new bonds is greater than the energy needed to break the "old" bonds, energy will be released overall by the reaction.

This type of bond energy does not apply to ionic bonds. When 2 atoms bind together to form a new...

WebStable molecules exist because covalent bonds hold the atoms together. We measure the strength of a covalent bond by the energy required to break it, that is, the energy necessary to separate the bonded atoms. Separating any pair of bonded atoms requires energy (see Figure 4.4). The stronger a bond, the greater the energy required to break it. WebChemical reactions that absorb (or use) energy overall are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products. Endothermic reactions are accompanied by a decrease in temperature of the reaction mixture. Chris.
