In a stationary state
WebMar 18, 2024 · Stationary states can also be described by the time-independent Schrödinger equation (used only when the Hamiltonian is not explicitly time dependent). However, it should be noted that the solutions to the time-independent Schrödinger equation still have time dependencies. Time-Dependent Wavefunctions WebNov 21, 2010 · The stationary states of an atom are numbered in order of increasing energy: E 1 < E 2 < E 3 < E 4 The lowest energy state (most stable) of an atom with energy E 1, is called the ground state of the atom. Other stationary states with energies E 2, E 3, E 4, … are called excited states of the atom.
