Lithium periodic table aqa
Web20 sep. 2024 · For lithium, there are two 1s electrons in an inner orbit and one 2s electron in the outer orbit. The same pattern holds for sodium and potassium. Even an atom with a very complex electron composition such as cesium still has the single s electron in its outer orbital (see figure below). Figure 6.9. 3: Celsium Orbitals.
