Bohr

WebBohr 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 jumps. WebJan 11, 2024 · Figure 20.3.1. The gold foil experiment was conducted under the supervision of Ernest Rutherford at the University of Manchester in 1909 by Hans Geiger and Ernest Marsden.

WebIt's all in the definition. The energy is defined as zero when the electron is an infinite distance from the nucleus. As the electron comes closer, the energy decreases, so the energy of the system becomes negative.
