Question

How many different f orbitals are there?

Answer 1

I'm not quite sure what you're asking. There are 4f, 5f, 6f, etc. How I do you want to count?
Or you might mean that there are 7 f orbitals. or something different?

Answer 2

I am little confused as well. The question that I have is that for verbatim. I kind of guessed it was 7, but I didn't know if there was something that I was missing since it is a little broad.
