I asked to find the number of Valence electron in Bismuth so my answer is 5. yes?

And 1 more question is I need to find the number of electrons in 4th level of Au
So is will be 32? Because if we look on Au in the 4th level so there 2 electrons in 4s 6 electrons in 4p 10 electrons in 4d and 14 electrons in 4f

Do I correct in my answers ?

Thanks.

I would say yes :)

hi.
thank you for answer.
so if I asked to find the number of Atomic orbital of: principal quantum number(n) and the orbital Angular momentum quantum number (L) of the orbital 2s


tell me if I correct n=2 and the Angular momentum L=0 ?

and in the orbital 6f n=6? And L=3?

thanks.

Sorry, this time it's really beyond me :(

:) that OK still thank you for all your help.

Pop, your answers are correct, but be careful. The azimuthal quantum number (also known as the orbital angular momentum quantum number) is usually denoted with a small cursive . Capital L is usually reserved for the angular momentum, itself (or the orbital angular momentum operator in Schrodinger's wave equation), not the quantum number.

yes truth I mean L=l.
thank you. :)
