A photon was absorbed by a hydrogen atom...

A photon was absorbed by a hydrogen atom in its ground state and the electron was promoted to the fifth orbit. When the excited atom returned to its ground state, visible and other quanta were emitted. Other quanta are:

A

1

B

2

C

5

D

10

Text Solution

Verified by Experts

The correct Answer is:
D
`N= .^(n)C_(2) = .^(5)C_(2) = 10`
