  • Quels sont les 3 postulats de Bohr ?

    La description du modèle de Rutherford-Bohr
    L'atome est représenté par un espace presque vide avec, au centre, un noyau massif et dense contenant les protons.
    Les électrons circulent autour du noyau de l'atome sur des couches électroniques.
    Il peut y avoir plus d'un électron par couche électronique.

  • Quel est le modèle de l'atome décrit par Bohr ?

    Réponse.
    Le modèle atomique de Bohr stipule que la quantité de mouvement angulaire �� d'un électron dans un atome est quantisé.
    Plus précisément, cela implique que �� ne peut être qu'un multiple entier de la constante de Planck réduite ℏ .

  • C'est quoi le postulat de Bohr ?

    1913 est l'annus mirabilis de Niels Bohr.
    Il écrit sa « trilogie », fondatrice de son modèle d'atome, toujours en vigueur de nos jours.
