Radial probability:
It is the probability of finding the electron within the spherical shell enclosed between a sphere of radius 'r + dr' and a sphere of radius "r' from the nucleus.

The radial distribution curve gives an idea about the electron density at a radial distance from the nucleus. The value of 4πr2ψ2 (radial probability density function) becomes zero at a nodal point, also known as a radial node.

The number of radial nodes for an orbital = n-l-1.

Where n = principal quantum number and l= azimuthal quantum number.

The relation between radial probability and radial probability density is given as:

Radial Probability = Radial Probability Density x Volume of spherical shell = 4πr2drR2nl(r)

The amplitude or intensity of the three-dimensional electron wave is known as Wavefunction and is represented by ψnlm (r,θ, Φ). It has both radial and angular parts.

ψnlm (r,θ, Φ) = Radial part x Angular part = Rnl(r) x Φlm(θ, Φ)

where,
Rnl(r) = Radial wavefunction
Φlm(θ, Φ) = Angular wavefunction

Is it possible to get the shapes of orbitals with the help of RADIAL PROBABILITY DISTRIBUTION curves?
