Lecture 11: Practice with Quantum Numbers

Node - region in space with zero probability of finding an electron. Result of destructive interference

2 Types

Angular - Planar or conical

1 S - Onodes , 2 S - 1 node , 3 S - 2 nodes

Values for each Orbital

0 - S orbital

1 - P orbital

2 - D orbital

Angular Nodes

﻿$\Psi$﻿ = 0

l - is the # of angular Nodes
