Which one of the following energy is stored in the links between the atoms?

Chemical energy is defined as the energy stored in the chemical bonds that connect atoms with other atoms and molecules. It is a form of potential energy that is released or absorbed during chemical reactions when these bonds are broken or formed [1]. While potential energy is a broader category that includes chemical energy, the specific energy stored in the links (bonds) between atoms is explicitly termed chemical energy [3]. In contrast, nuclear energy is stored in the nucleus (core) of an atom, involving protons and neutrons rather than the links between atoms. Thermal energy refers to the internal energy of a system due to the kinetic motion of its particles. Therefore, the energy specifically residing in the inter-atomic links is chemical energy [1].
