So the question here asks how many orbitals are there in an atom with each of the following quantum, principal quantum numbers.
00:07
So a is 1, b is 2c, 3, d, 4, and e is 5.
00:15
So essentially, in order to determine the number of orbitals, we can just take the principal quantum number n and then square it.
00:22
So this is because, for example, when we actually have, let's say, a, let's see what the first example here.
00:30
So if we have a principal number being one, we know that the orbitals that exist within these principal number is only going to be l equals 0, so that corresponds to the s orbital.
00:42
And, of course, there's only one orbital within the s subshell...
