In a chemical compound, where is the chemical energy primarily stored?

• A. In the electrons of the outermost shell only
• B. In the intermolecular forces between molecules
• C. In the bonds between atoms
• D. In the nucleus of each atom

Answer: (C)

Verified step by step guidance

1. Understand that chemical energy in a compound is related to how atoms are connected and interact with each other.
2. Recall that atoms form chemical bonds by sharing or transferring electrons, primarily involving the outermost (valence) electrons.
3. Recognize that the energy stored in a compound is mainly due to the potential energy within these chemical bonds between atoms.
4. Differentiate this from energy stored in the nucleus (nuclear energy) or in intermolecular forces, which are weaker and not the primary source of chemical energy in a compound.
5. Conclude that the chemical energy is primarily stored in the bonds between atoms, as these bonds hold the atoms together and their formation or breaking involves energy changes.
