The electron in the hydrogen atom undergoes transition from higher orbitals to orbital of radius 211.6 pm. This transition is associated with:

A

Lyman series

B

Balmer series

C

Paschen series

D

Bracket series

Text Solution

Verified by Experts

The correct Answer is:
B
`r = 0.529 xx (n^(2))/(Z)`
`r = 211.6 pm = 2.11 Å`
`rArr 0.529 xx (n^(2))/(Z) = 2.11 Å`
n = 2 (Balmer series ).
