The plots of radial distribution functions for various orbitals of hydrogen atom against 'r' are given below. The correct plot for 3 s orbital is:

Correct answer

2

Step-by-step solution

Calculate the number of radial nodes using the Number of radial nodes = n - ℓ - 1 = 3 - 0 - 1 = 2 Radial nodes= number of cuts on x-axis ( r). The curve should start from zero. It can be positive or negative. Size of the curve increases after touching the x- axis every time . By keeping all this, we get the following curve: Therefor corresponding graph is (C) Hence, answer is ( 3 )
