Masse electron

Construire un atome de protons, de neutrons et d'électrons, et voir comment l'élément, la charge et la masse changent. Ensuite, jouer à un jeu pour tester vos idées!

This is an explanation for why you can't force mass into smaller volumes.

Electron. Particule fondamentale ponctuelle (son diamètre est considéré comme nul), d'une masse me = 9,109.10-31 kg, portant une charge -e (e étant la charge élémentaire, c'est-à-dire qu'il n'en existe pas de plus petite) = -1,602.10-19 C.

Isotopy and Isotopes; definitionquestions and solution.     Isotopy and isotopes Isotopy can be defined as a process/occurence/phenomenon whereby an element has the same atomic number (i.e the number of protons) but different mass number (i.e number of neutrons).  Proton  Neutron  Electron Isotopes are the elements that have the same atomic number (number of protons) and different mass number (number of neutrons). Examples of isotopes are; Chlorine  3517Cl  3717Cl Oxygen    168O  178O  188O…

You've heard of electrons—they're the negatively charged subatomic particles that swarm about the nucleus of every atom. But if you take an electron, blow it up to more than 200 times its mass and make it blink out of existence faster than a bullet can leave a gun, you've got a muon (pronounced not like a cow but like a kitten: myoo-on). Why is such a heavy, short-lived particle important? Scientists aren't sure, but they have some fascinating hunches.
