Where is chemical energy stored in chemical compounds?

• A. In the free electrons outside the compound
• B. In the protons of the atoms
• C. In the nucleus of atoms
• D. In the bonds between atoms

Answer: (D)

Verified step by step guidance

1. Understand that chemical energy is the energy stored within chemical compounds due to the arrangement and interactions of atoms.
2. Recognize that atoms consist of protons, neutrons, and electrons, but the energy relevant to chemical reactions is not stored in the nucleus or in individual protons or electrons alone.
3. Recall that chemical bonds form when atoms share or transfer electrons, creating a stable arrangement that contains potential energy.
4. Identify that this potential energy stored in the bonds between atoms is what we call chemical energy, which can be released or absorbed during chemical reactions.
5. Conclude that the correct location of chemical energy is in the bonds between atoms, not in free electrons, protons, or atomic nuclei.
