Which of the following plots of radial-probability function 4 π r 2 ψ 2 is/are correct (i) (ii) (iii) (iv)

Options

AOnly i
Bii and iii
Ci and iii
Dall

Correct answer

C. i and iii

Step-by-step solution

(i) and (iii) are correct graph according to their orbitals 1s & 3s respectively. Graph of 2s: Graph of 3p: (i) - (iv) - As all graphs for 4 π r 2 Ψ 2 v/s r start from origin. So it is incorrect.
