Notes

In the Bohr model, $n = 1, 2, \dots, \infty$ is related to the binding energy of an electron and the radius of spherical orbits (principal axis of the elliptic orbits).

For an electron in an $H$ atom, the semi-classical radius of its orbit is $r_{n} = a_{0} n^{2}$ and its binding energy is $E_{n} = E_{H} / n^{2}$ .

Dans le modèle de Bohr, $n = 1, 2, \dots, \infty$ est associé à l'énergie de liaison d'un électron et au rayon des orbites sphériques (axe principal des orbites elliptiques).

Pour un électron dans un atome $H$ , le rayon semi-classique de son orbite est $r_{n} = a_{0} n^{2}$ et son énergie de liaison est $E_{n} = E_{H} / n^{2}$ .
