Verified step by step guidance

Understand that energy in a molecule is primarily stored in the chemical bonds between atoms. These bonds are formed by the interactions of electrons, which are involved in the sharing or transfer of electrons between atoms.

Recognize that the energy stored in chemical bonds is due to the potential energy of the electrons in these bonds. When bonds are broken or formed, energy is either absorbed or released.

Consider the role of electrons in chemical bonding. Electrons in the outermost shell, or valence electrons, are the ones involved in forming bonds, and thus, they play a crucial role in storing energy.

Differentiate between the types of bonds: covalent bonds involve sharing of electrons, while ionic bonds involve transfer of electrons. Both types of bonds store energy, but in different ways.

Note that while the nucleus of an atom contains a significant amount of energy (nuclear energy), this energy is not typically involved in chemical reactions, which primarily involve the electrons and bonds between atoms.
