Lithium atom

Référence de la vidéo 11924979
Lithium atom. Diagram of an atom of the element lithium, pulling back from the central nucleus to reveal the surrounding electron orbitals. Lithium is the third element, and has three protons (red) in its nucleus, along with four neutrons (blue). Lithium has three electrons, and each of its orbitals can hold a maximum of two. Orbitals are filled from the lowest energy (nearest the nucleus) first, so there are two electrons in the inner 1s orbital, and one in the higher energy 2s orbital (green spheres). For clarity, solid lines show the paths of the electrons. In reality, electrons can be found anywhere, and the shape of each orbital is based only on where it is most likely to be found. For the same clip on a transparent background, see clip number K002 3054.
