If the following atoms and molecylates for the transition from `n = 2` to `n = 1`, the spectral line of minimum wavelength will be produced by

A

hydrogen atom

B

decterium atom

C

uni-ionized helium

D

di-ionized lithium

Text Solution

Verified by Experts

The correct Answer is:
D
`(1)/(lambda) = RZ^(2) ((1)/(1^(2)) - (1)/(2^(2)))`
For di-ionised lithium the value of `Z` is maximum.
