Question

Which of the following plots of radial-probability function $4\pi r^{2}\psi^{2}$ is/are correct

(i)

(ii)

(iii)

(iv)

• A. Only i
• B. ii and iii
• C. i and iii
• D. all

Answer 1

Answer: (C)

(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 $4\pi r^{2}\Psi^{2}$ v/s r start from origin. So it is incorrect.
