Once the thermal velocity of electrons exceeds their "escape velocity" from atoms, the electrons break loose from their orbits and roam free. The presence of freely moving electrons is the defining characteristic of a plasma. ... when ... the temperatures are so high that atoms are torn apart into charged nuclei and free electrons, their ability to radiate light is much enhanced. Thus plasma glows. 2, record 1, English, - free%20electron

Électrons libres. Ce terme s'applique à une théorie des métaux proposée [...] par le physicien allemand P. Drude et [...] [par] A. Sommerfeld [...]. Seuls les électrons de valence d'un élément métallique sont responsables de la conductivité. C'est eux que désigne le terme électrons libres. Alors que les électrons des couches internes sont considérés comme étant fixés au voisinage d'un atome bien particulier, les électrons libres se déplacent, indépendamment les uns des autres, dans l'espace délimité par les surfaces du métal. Ils sont soumis à un potentiel qui est la somme des potentiels moyens dus aux ions métalliques du réseau et à tous les autres électrons libres. 1, record 1, French, - %C3%A9lectron%20libre
