WebLe béryllium est un élément chimique de numéro atomique 4, ce qui signifie qu’il y a 4 protons dans son noyau. Le nombre total de protons dans le noyau est appelé le numéro atomique de l’atome et reçoit le symbole Z. La charge électrique totale du noyau est donc +Ze, où e (charge élémentaire) vaut 1 602 x 10-19 coulombs.
