Question
The photon radiated from hydrogen corresponding to 2nd line of Lyman series is absorbed by a hydrogen like atom ′X′ in 2nd excited state. As a result the hydrogen like atom ′X′ makes a transition to nth orbit. Then :
Options
A.X = He+, n = 4
B.X = Le++, n = 6
C.X = He+, n = 6
D.X = Li++, n = 9
= 13.6Z2
