JEE Main 2021 (Online) 25th February Morning Shift Chemistry - Structure of Atom Question 113 English
The correct plot for 3s orbital is :
(B)
(A)
(C)
(D)

Explanation

Number of radial nodes = n – (l + 1)

For 3s orbital n = 3, l = 0

Number of radial nodes = 3 – 0 – 1 = 2

It is correctly represented in graph of option D.
