Electron

an elementary particle with a negative electrical charge and a mass 1/1837 that of the proton. Electrons surround the nucleus of an atom because of the attraction between their negative charge and the positive charge of the nucleus. A stable atom will have as many electrons as it has protons. The number of electrons that orbit an atom determine it...

Electron

The electron (symbol: {SubatomicParticle|Electron}) is a subatomic particle with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1...

Electron

[bird] Electron is a genus of the motmots, a family of Neotropical near passerine birds. The genus has two species: Both inhabit humid evergreen tropical forest. Both occur in Central America, and the broad-billed motmot occurs in a large region of South America as well. They are distinguished from other motmots by their much wider bills. T...
