Atomic Structure - Result Question 77

####53. For the given orbital in Column 1, the Only CORRECT combination for any hydrogen-like species is

(a) (II) (ii) (P)

(b) (I) (ii) (S)

(c) (IV) (iv) (R)

(d) (III) (iii) (P)

Show Answer

Answer:

Correct Answer: 53. (c)

Solution:

  1. Correct : $2 s$ orbital has one radial node.

No of radial node $=n-l-1=2-0-1=1$

Also, when radial part of wave function $(\psi)$ is plotted against " $r$ “, wave function changes its sign at node.
