Question

What is radical and angular

Answer 1

A radial node is a sphere (rather than an angular node which is a flat plane) that occurs when the radial wavefunction for an atomic orbital is equal to zero or changes sign.

Answer 2

Helloo!!

1. Radial nodes are nodes which are areas of zero probability of finding an electron and radiate like circles away from the nucleus.

2. Angular nodes can be visualized on boundary surface diagrams as planar nodes that separate the different signs of the orbital. 

hope it helps
