The Strength of the Strong Force
Parmi les quatre forces de la nature, la plus puissante est appelée la strong nuclear force. Elle binds les particules de quarks ensemble, et ces quark particles forment des protons et des neutrons. Celles-ci restent ensemble compactly pour former le nucleus.
La charge des protons est positive et celle des neutrons est neutral. Les protons chargés électriquement se repel entre eux. Par conséquent, l’arrangement de plusieurs protons dans le nucleus est complexe. Cependant, sauf pour l’hydrogène, le nombre de protons augmente dans les autres éléments. Par exemple, le helium nucleus contient deux protons et l’uranium en contient 92.
Ces protons et neutrons peuvent adhere les uns aux autres uniquement par la strong force. La electromagnetic force qui agit entre les protons est surmontée par la dominance de la strong force. C’est pourquoi on l’appelle la strong nuclear force.
