Helium electronic structure. Animation of the electronic structure of the element helium. An atom of this element has 2 electrons, shown here as black dots in a shell around the nucleus (centre). The animation zooms in to show the two electrons in the first shell (the 1s orbital). The electron configuration is 2. The isotope shown here is helium-4, with a nucleus of 2 protons (red) and 2 neutrons (blue). All isotopes of an element have the same electronic structure. | |
