What is the electron rotational speed around the nucleous?
The motions of electrons in atoms and molecules are described by quantum
mechanics, and in that context the question of how fast it is moving around
the nucleus loses meaning.
Classical mechanics does not apply to atoms and molecules. Even in the most
simple case, the hydrogen atom, classical physics predicts that the electron
would spiral into the nucleus, which of course does not occur.
