So let's look at the shape of our S. S has a spherical shape. And what that basically means what this shape means is that there's a 90% chance that our electron will be found within this sphere. In other words, if we know that our N is equal to zero, or actually M equals one, m can't be zero. If M equals one, that means our L equals zero. So that means our subshale must be S. And that means that if this was our proton, there is a 90% chance, 90% probability that our electron is found within this skier. Likewise, let's look at the P orbital.
