Question

what are radial and angular wave function

Answer 1

An orbital is a mathematical functioncalled a wave function that describes an electron in an atom. The wave functions, ψ, of the atomic orbitals can be expressed as the product of a radial wave function, R and an angular wave function, Y.

Answer 2

The wave-function, which persists for nuclear orbital, is distributed into the two radial and angular wave-functions.

An orbital is a numerical function named as a wave function that defines an electron in an atom. Radial wave functions for a given atom depend only upon the interval, r from the nucleus.

Angular wave functions rely only upon direction, and, in effect, define the appearance of an orbital.
