stationary state
... • When an electron is in one of the quantized orbits, it does not emit any electromagnetic radiation; thus, the electron is said to be in a stationary state. • The electron can make a discontinuous emission, or quantum jump, from one stationary state to another. During this transition it does emit r ...
