WebAtomic Structure. What are Electron Shells (energy levels)?. Electrons in atoms are in shells (shown as circles around the nucleus). The shells can also be called energy levels. We will use the term shell rather than energy … WebThe number of valence shell electrons an atom must gain or lose to achieve a valence octet is called valence. In covalent compounds the number of bonds which are characteristically formed by a given atom is equal to that atom's valence. From the formulas written above, we arrive at the following general valence assignments:
