Question

The above radial probability graph represents:

• A. 2s
• B. 3d
• C. 4p
• D. 1s

Answer 1

The correct option is C 4p

From the radial probability plot, only the number of radial nodes can be determined which is 2.
Radial node can be obtained by the formula $n-l-1$

(a) Number of radial nodes in 2s = $2-0-1=1$
(b) Number of radial nodes in 3d = $3-2-1=0$
(c) Number of radial nodes in 4p = $4-1-1=2$
(d) Number of radial nodes in 1s = $1-0-1=0$

Thus option (c) is the correct answer
