Max # of electrons in an orbit

  1. Jul 5, 2010 #1
    what is the maximum number of electrons allowed in each of the first 5 orbits of an atomic particle? Is it the same for all elements? or do different ones hove a different maximum numver of electrons possible of being in an orbit?

    Don't say atomic particle. Just call it an atom.

    Have you heard of the [tex]2{n}^{2}[/tex] rule. That's the maximum number of electrons in the [tex]{n}^{th}[/tex] orbit. It is the same for all elements.

    Thank you, that equation was exactly what I was wanting, I figured it out once about 7-6 years ago when I was reading a book on quantum physics and couldn't remember it so I was going to try to figure it out again but you have saved me the trouble. Thanks again.
