Which energy type relates to the energy stored in chemical bonds?

• A. Radiant
• B. Mechanical
• C. Nuclear
• D. Chemical

Answer: (D)

Chemical energy is the energy stored in the bonds that hold atoms together in molecules. The energy comes from the bonds themselves—when bonds are broken and new bonds form during reactions, energy is released or absorbed. This is different from radiant energy (energy carried by light), mechanical energy (energy of motion or position), and nuclear energy (energy stored in atomic nuclei). A common example is fuel, where the chemical bonds store energy that is released as heat and light when burned.
