Question

Which among the following is true for radial probability distribution curve?

• A. The number of maxima in the 3s orbital is 3
• B. The number of radial nodes in 4s is equal to one less than the number of humps in the curve
• C. Radial probability distribution function explains penetration effect
• D. At the node, the value of radial function changes from positive to negative

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A The number of maxima in the 3s orbital is 3
B The number of radial nodes in 4s is equal to one less than the number of humps in the curve
C Radial probability distribution function explains penetration effect
D At the node, the value of radial function changes from positive to negative



For any subshell, say 2s, the $\Psi$ vs r curve is like
