To gain an electron from any atom
Definitely, the more you research into something the more information on it you’ll get, they could very well realize that with the new information their old faces were incorrect
The magnitude of the orbital angular momentum of the electron is doubled when the radius of the electron orbit increases by a factor of four.
<h3>
What is orbital angular momentum?</h3>
The orbital angular momentum is the sum of angular momenta of all electrons, it is the rotational analog of the linear momentum.
The formula of angular momentum
