Question

In hydrogen atom, electron jumps from the 3'' orbit to the
1" orbit. The change in angular momentum is.............
(a) 105x10-54J b) 2-11X10-34 Js
(c) 3.16x104
(d) 4.22x103* Js​

Answer 1

b)2.11 × 10^-34

Explanation:

3rd orbit angular momentum = 3h/2 pi

1st orbit angular momentum = h/2 pi

Change in angular momentum = 3h/2 pi - h/2 pi

= 2h/2 pi

= h / pi

= 6.63 × 10^-34 / 3.14

= 2.11 × 10^-34
