Which of the following radial probability density graph corresponds to `l = 2` for which the least value of `l = 2` is allowed ?

Explanation

Option c represents the distribution of `l = 2` for H atom
a. Two nodes `(n-1-1) = 2(n-2-1)= 2` :.n= 5(High value of n)
b. One node`(n-2-1)= 2= 1,n= 4`
Zero node `(n-2-1)= 0,n = 3 ("Minimum value of n white l = 2 is allowed")`
d. Graph does not correspond to any radial distribution curve
