The Bohr Atom
... An accelerated charged particle radiates electromagnetic waves. It is straightforward to show that, in the case of the hydrogen atom, as the electron loses energy, it moves into an orbit of smaller radius, loses energy more rapidly and spirals into the nucleus within about 10−10 seconds. This cannot ...

... • When Main Group elements react, electrons can be transferred (usually from a metal to a nonmetal) to form ionic bonds. In other cases, pairs of electrons can be shared (usually between nonmetal atoms) to form covalent bonds. In both cases valence electrons are somehow “rearranged” when new chemica ...

... The new atom laser emits pulses of coherent atoms, or atoms that "march in lock-step." Each pulse contains several million coherent atoms and is accelerated downward by gravity. The curved shape of the pulses was caused by gravity and forces between the atoms. (Field of view 2.5 mm X 5.0 mm.) ...
