Définition : On appelle particule élémentaire toute particule indivisible (cette notion est évidemment liée à
l'état des connaissances actuelles).
Les protons, les neutrons et les électrons sont des particules élémentaires.
Charge élémentaire : La charge élémentaire est la plus petite charge électrique susceptible d’exister de façon
stable.
Sa valeur est e=1,60× 10 −19 C .
Remarque : Toute charge électrique q est égale à un multiple de la charge élémentaire.
q=n×e avec n entier
2.
Particules constituant l’atome
L'atome est constitué à partir de 3 particules élémentaires : le
proton
, le neutron et l'électron .
Autour du noyau formé de neutrons et de protons, les électrons
sont en mouvement rapide.
Caractéristiques des particules élémentaires dans
l'atome
Proton mp = 1,673x10 -

Neutron mn = 1,675x10 -

q = 0 r = 1,2x10 -
15m
Électron me = 9,109x10 -
31
kg
q = -e
Les ordres de grandeur des masses des particules élémentaires sont:
10
- 27kg pour un nucléon.
10
- 30kg pour un électron.
Le noyau d’un atome est représenté symboliquement par la notation :
Z A X avec { X: symbole de l'élément chimique Z: numéro atomique (représente le nombre de protons)
A: nombre de masse (représente le nombre de nucléons)
Remarque : L’atome est une entité électriquement neutre.
Le nuage électronique est donc chargé
négativement et compte autant d’électrons qu’il y a de protons dans le noyau.
La charge du noyau est q N =+Z×e.
La charge portée par les électrons est q e =−Z×e.
Exemple : Soit l’atome de carbone dont le noyau est noté 6 14 C ..
