Scandium electronic structure, animation

Référence de la vidéo 12081492
Scandium electronic structure. Animation of the electronic structure of the element scandium. An atom of this element has 21 electrons, shown here as black dots in shells around the nucleus (centre). The electrons are in four shells. The animation zooms in to show the two electrons in the first shell (both in the 1s orbital). There are eight electrons filling the second shell (the 2s and 2p orbitals). There are nine electrons filling the third shell (the 3s and 3p and 3d orbitals). Finally, there are two electrons in the fourth shell (the 4s orbital). The electron configuration is 2, 8, 9, 2. The isotope shown here is scandium-45, with a nucleus of 21 protons (red) and 24 neutrons (blue). All isotopes of an element have the same electronic structure.
