Okay, so this question asks about the three main quantum numbers that is required to describe the distribution of electron density.
00:12
So the first quantum number we know is n, which is called the principal quantum number.
00:33
So this quantum number actually describes the most probable distance of electrons from the nucleus.
00:44
So from nucleus, so it basically tells you the electron cell, right, the shared electrons.
01:17
And the second quantum number, we call that the orbital angular momentum quantum number, right? which is l.
01:29
So it's called the orbital angular momentum quantum number.
01:44
So what this basically describes is it determines the shape of the orbital shape.
02:12
So you can say it's basically described the angular distribution of the electrons...
