It can be understood from the classical picture that if all electrons are orbiting in the same direction (higher orbital angular momentum) they meet less often than if some of them orbit in opposite directions. In the latter case the repulsive force increases, which separates electrons. This adds potential energy to them, so their energy level is higher.

In QM, energy levels of atoms are quantized. This means that rather than the system being able to have any energy, there are instead only discrete energy levels the system can be observed to be in. The "lowest energy state" is just the state with the smallest amount of energy.

WebSummary. Photoelectron spectroscopy (PES) is an experimental technique used to determine the relative energies of electrons in atoms and molecules. Photoelectron spectrometers work by ionizing samples using high-energy radiation (such as UV or x-rays) and then measuring the kinetic energies (. KE.

WebRule #1: To write the ground state electronic configuration of an atom, electrons are added to the lowest energy orbitals, giving each orbital two electrons. This is called Aufbau Principle. The lowest energy arrangement of electrons is called Ground State. According to Aufbau principle, electrons first occupy 1s orbital, then 2s and 2p. WebNote: Energy eigenfuctions characterize stationary state. We cannot track the electron and know its energy at the same time. If we know its energy, we can only predict probabilities for where we might find it if we tried to measure its position. If we determine the position of the electron, we lose the energy information.

WebAn excited atom has an electron or electrons which are not in the lowest energy state. Excited atoms are unstable energetically. The electrons eventually fall to a lower level. * is used to indicate an excited atom. For example: *Li 1s 2 13p1. (The ground state for Li is 1s 2s .)
