Total no. of orbitals = \(n^2\) where n is no. of the orbit
So for n=5
Total no. of orbitals = \(5^2\) = 25
There are 25 orbitals for n = 5.
Thanks for replies.. i was wondering
one s+ three p+ five d+ seven f which makes it 16. Which are the nine left?
These are nine g orbitals which are usually vacant.
