So the question here asked, how many values of El can be? Um, found when you have the principal quantum number of and is equal to four. So we know that l could be determined by taking, um, the ranges of zero to, um and minus one. So in this particular case, we're gonna have all the numbers that exists between 012 and three, which shows that within this particular principal quantum number, there is going to be a s orbital P orbital, the orbital and also f orbital.
