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 radial node.
The number of radial nodes for an orbital = n-l-1.
Where n = principal quantum number and l= azimuthal quantum number.
Since n = 3 and l = 1 for the given atomic orbital (3p orbital), the number of radial nodes = 3-1-1 = 1.
Hence the radial probability distribution curve should contain a trough representing a radial node.
There are two graphs showing this behavior. The correct one is option-3, since the distance of maximum probability occurs at greater distance. I mean the crest with more height should be farther from smaller crest
1) Which of the above curve corresponds to s orbital?
2) Mention the orbitals which can show radial probability distribution curve given under option-1?
3) Is it possible to get the shapes of orbitals with the help of these curves?
4) What is exactly radial node? (copied from adichemistry.com). What s the difference between angular node and radial node?
5) Calculate the number of radial nodes for 1s, 2s, 3s, 2p, 3p, 4p, 3d, 4d & 5d orbitals.
