Which of the following contains chemical energy? a.) atoms that in motion b.) the nucleus of an atom c.) a bond between two atoms d.) the electrons of an atom

Correct option is C.

Explanation: Chemical energy is the energy which is related to the chemical bonds of atoms and molecules. It is released in the chemical reaction.

Option A is related to the kinetic energy of the atom because the atom is in motion.

Option B is related to the nuclear energy of the atom as it is explaining about the nucleus of the atom.

Option C is related to the chemical energy of the molecule as there is the formation of a bond between two atoms.

Option D is related to the kinetic energy of the atom as we know that the electrons are in constant motion.
