Hello everyone,

Recently I have been watching Buckys tutorial from the 22nd October 2011 titled "Chemistry Lesson - 11 - Figuring Out the Quantum Numbers". I understand how to do sizes 1 and 2 but unsure on how to do the 3rd size. I feel that having the knowledge of size 3 and how that is done will help me greatly on understanding the other sizes and continuing on the other sizes.

If you could help it would be much appreciated, here is the table:

If you understand or recognize this from Buckys tutorial then please, could you help me? What would n3 be?
