3.3 Why do atoms radiate light?
... • This explains too, why atoms can be stable, although they have a rotational momentum (in the classical description they would always radiate light and thus be destroyed). This classical explanation results from the wrong picture, that the electron is moving through the orbital, leading to a steady ...

Atomic Orbitals - Daytona State College
... Atomic orbitals are typically categorized by n, l, and m quantum numbers, which correspond to the electron's energy, angular momentum, and an angular momentum vector component, respectively. Each orbital is defined by a different set of quantum numbers and contains a maximum of two electrons. The si ...
