Difference between Energy level and Excited state

Energy level vs. Excited state

A quantum mechanical system or particle that is bound—that is, confined spatially—can only take on certain discrete values of energy. In quantum mechanics, an excited state of a system (such as an atom, molecule or nucleus) is any quantum state of the system that has a higher energy than the ground state (that is, more energy than the absolute minimum).

Similarities between Energy level and Excited state

Energy level and Excited state have 16 things in common (in Unionpedia): Atom, Atomic nucleus, Atomic orbital, Bound state, Electron, Energy, Ground state, Molecule, Photon, Quantum mechanics, Quantum state, Rydberg formula, Spectral line, Stationary state, Temperature, Wave function.
