The correct response is:
Chemical energy is the energy stored in the bonds between atoms and molecules.
To arrive at this answer, you can break down the other response options:
- Energy due to the jiggling motion of molecules refers to thermal energy, also known as heat.
- Energy carried by electrical current is known as electrical energy.
- Energy stored in the bonds between the parts of an atomic nucleus is nuclear energy.
By process of elimination, we can conclude that the correct definition of chemical energy is the energy stored in the bonds between atoms and molecules.
