How many possible orbitals are there for n= 4?
16. n^2= number of orbitals
To determine the number of possible orbitals for a given value of n (the principal quantum number), you need to remember that the number of orbitals is equal to n^2.
In this case, n = 4. So, to find the number of orbitals, you would simply square the value of n:
4^2 = 16
Therefore, there are 16 possible orbitals for n = 4.
