Helium electron configuration. Illustration of the atomic structure and electron configuration 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 two electrons are 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 | |
