Question

2. If the distance between electron & nucleus in nth shell
H-atom is 4.761 4 , then find the angular
momentum in nth shell.​

Answer 1

Answer:

Bohr radius of n

th

orbit(

R

n

) =

R

0

Z

n 2

Where

R

0

0.529A

For hydrogen,

Z=

1

GIven ,

R

n

4.768 A

˚

⟹

0 . 5 2 9

4 . 7 6 8

=

n 2

n=

3

The angular momentum (mvr) =

2 π

n h

⟹
