WebQuantum jumps. Bohr postulated that electrons in the atom move in what he called energy states. These energy states are “stationary” (of fixed energy, not fixed position) at different distances from the nucleus. He further reasoned that electrons can undergo transitions from one energy state to another. Bohr called these transitions quantum ...
