Explanation:

The image shows the arrangement of electrons around the nucleus of different atoms in concentric circles. These circles represent electron energy shells where electrons are located. Compounds are combinations of different elements, chemical bonds are forces between atoms, and isotopes are variants of an element with different numbers of neutrons. None of these fit the description as well as energy shells.

Answer:

energy shells
