These energies are comparable to the energies of chemical bonds.
- These energies are comparable to the energies of chemical bonds.
- So this force is responsible for magnets attracting or repelling, and it also gives us chemical bonds between atoms to form molecules.

Morphology
This is fully compositional: 'chemical' specifies the domain (relating to chemistry) and 'bond' denotes a connection or attraction, so their combination directly yields the meaning of an attraction between atoms or ions. The structure is cross-linguistically common (e.g. Spanish 'enlace químico'), so a B1 learner who knows both constituents will readily infer the MWE meaning.
Etymology
Chemical bond uses bond like a rope or link that holds things together and chemical to show it is about atoms and molecules. So the image of atoms 'holding together' explains why it means the pull that keeps atoms joined in a molecule.
