# How many angular nodes are in a d_(z^2) orbital?

Aug 22, 2017

The number of angular nodes in a "d"_text(z²) orbital is two.

#### Explanation:

For any orbital,

$\text{Total no. of nodes} = n - 1$

$\text{No. of angular nodes} = l$

$\text{No. of radial nodes} = n - l - 1$

It is easy to see the two angular (conical) nodes in a 3"d"_text(z²) orbital.

A 4"d"_text(z²) orbital has the same two conical nodes plus a radial (spherical) node.

A 5"d"_text(z²) orbital has the same two conical nodes plus two radial (spherical) nodes.
