Question

How many nodes are present in 3-p orbitals? Represent diagrammatically.

Answer 1

The number of radial nodes, otherwise known as spherical shell nodes, is given by

n-l-1 =3-1-1 =1 radial node

in the 3p orbital

The number of angular nodes, is given by l, so there is

l=1 angular node

in the 3p orbital

Thus, the total number of nodes is given by

n-1 =3-1 =2

therefore, total number of nodes in 3p orbital is 2
