When a hydorgen atom is excited from ground state to first excited state then :

A

Its kintic energy increases by `10.2 eV`

B

Its kinetic energy decreases by `10.2 eV`

C

It potential energy increases by `20.4 eV`.

D

Its angular momentum increases by `1.05 xx 10^(34) J-s`

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
`|DeltaK| = 13.6[(1)/(1^(2)) - (1)/(2^(2))] = 10.2 eV` ltbr gt `|DeltaU| = 27.2 [(1)/(1^(2)) - (1)/(2^(2))] = 20.4eV`
`DeltaL = (2h)/(2pi) - (h)/(2pi) = (h)/(2pi)`
