light element  

Définition

  • Astronomers often refer to hydrogen or helium, including any of their isotopes, as being light elements; all other elements are regarded as being heavy elements. Alternatively, a 'light element' may refer to any chemical element produced during the first few minutes after the Big Bang, including, in addition to hydrogen and helium, lithium, beryllium, and boron.
