### Quantum Numbers

Hi,
Could someone explain to me how many subshells there would be if n=4?

There are four subshells. Since n=4, l can only be four different values which are 0,1,2, and 3 which correspond to s, p, d, and f.

### Re: Quantum Numbers

Remember, the angular momentum quantum number, l, determines the subshell. n can have integer values greater than 0, in this case n=4 is given.

l can have integer values from 0 to n-1, so if n=4, l can = 0,1,2,3.

So, in a ground state there are a possible of four subshells: l=0 would be the s subshell, l=1 would be the p subshell, l=2 would be the d subshell, and l=3 would be the f subshell.
