WebSep 5, 2024 · A chemical bond between atoms or ions is a force of attraction. Bonds are created when electrons are exchanged or transferred by atoms. Two atoms share one or more electrons in a covalent bond. To render their outer electron shells more stable, atoms form chemical bonds. Why do bonds form? Bonds form when atoms share or transfer … WebA chemical reaction’s activation energy is the “threshold” level of energy needed to break the bonds in the reactants. Once those bonds are broken, new arrangements can form. Without an enzyme to act as a catalyst, a much larger investment of energy is needed to ignite a chemical reaction (Figure 2).
