Question
The wave function () of 2s is given by 2s = 2 / 2 / 0 1 2 a r e a r a At r = r0, radial node is formed. Thus, r0 in terms of a0 (A) r0 = π0 (B) r0 = 2a0 (C) r0 = 4a0 (D) r0 = a0
Answer: B
π‘ Solution & Explanation
At node ο2s2 = 0 ο2s = 0 So, ο·ο· οΈ οΆ ο§ο§ ο¨ ο¦ ο a r = 0 2 β 0 a r = 0 2 β 0 a r ο r0 = 2a0
