Question

What is the orbit angular momentum of electron present in 3rd orbit of h-atom?

Answer 1

Answer

L=√l(l+1)ħ

In simplest terms, orbital angular momentum is quantized and can be computed using the orbital angular momentum quantum number l:

L=√l(l+1)ħ

Answer 2

Answer:

2.111 ×10^-34 Js -  the orbit angular momentum of electron present in 3rd orbit of h-atom

Explanation:

Angular momentum = L= mvr = n h/2 × 3.14 i.e pi

So,

n=3

L = 3h / 2 × 3.14 = 1.5 h / 3.14 ....(1)

Similarly, n=1

L = 1h/2 × 3.14 = 0.5h/ 3.14 ....(2)

So, (1)-(2);we get

h/3.14 = (1.5-0.5)

After solving,

L = 2.111 ×10^-34 Js
