1. In the paper, Heisenberg formulated quantum theory without sharp electron orbits . 2. Solem discovered electron orbits perpendicular to an applied electric field ( 1987 ). 3. This means that the innermost electrons orbit at approximately 1 / 4 the Bohr radius. 4. Ordinarily, a single electron orbits an hydrogen atom. 5. Essentially the electron orbits the donor ion within the semiconductor material at approximately the bohr radius. 6. ;1904 : Hantaro Nagaoka proposes an early nuclear model of the atom, where electrons orbit a dense massive nucleus. 7. The quantum number first appeared in the Bohr model where it determines the radius of each circular electron orbit . 8. The quantum characteristics of excimer can be described by a stable core molecular ion surrounded by Rydberg-like electron orbits . 9. In 1904, Hantaro Nagaoka proposed an early nuclear model of the atom, where electrons orbit a dense massive nucleus. 10. To overcome wallpaper's stodgy image, designers adopted modern motifs like rocket ships and television antennas, ranch houses and electron orbits .
