is an 8s subshell/orbital possible?

[robert zellmer]

I got a question about 6.61 (14th & 13th ed.), 6.55 (12th ed.), 6.53 
(10th and 11th ed.).
This question asks which are impossible combinations  of n and l. Hopefully
you did this problem and understood there is no 1p or 2d.

I'm sending this to ask you about something like a 6f.  Can that exist?  Of
course it does.  Think about exp 7 you did and things we covered in class.
Hydrogen has 1 electron in the 1s subshell in its ground state.  Are there
other levels, such as the 2nd (n=2), 3rd (n=3),  etc.?  Of course there 
are.
There's  simply no electrons present in those shells until the 1s 
electron is
excited there by an input of energy to get an excited state.  Just 
because there
are  no electrons in an 8s or 6g or 10d, etc., subshell in the ground 
states of
any of the known elements doesn't mean the subshells don't exist. Remember,
there was a time we didn't even know about the elements in the bottom two
rows with electrons in the 4f and 5f.  Does that mean they didn't 
exist?  Of
course they did, we just hadn't discovered elements with electrons in those
subshells yet.

I hope this clears up any questions about this.
