Question

Volumetric probability distribution is given by:

• A. $\psi$
• B. $4\pi r^2|\psi {|}^{2}dr$
• C. Principal quantum number $n$ and azimuthal quantum number $l$
• D. H

Answer 1

The correct option is B $4\pi r^2|\psi {|}^{2}dr$

Volumetric probability distribution gives the probability for an electron to be found anywhere in a shell of thickness dr on the surface of a sphere located at a distance r from the nucleus.
It is obtained by squaring the wave function and multiplying by $4\pi r^{2}dr$.
