The shortest wavelength of the spectrum ...

The shortest wavelength of the spectrum line is that of electron being transits into atom to ion from n = 2 to n = 1 for .......

A

hydrogen atom

B

deuterium atom

C

singly ionized helium

D

doubly ionized lithium

Text Solution

Verified by Experts

The correct Answer is:
D
doubly ionized lithium
`(1)/(lamda)=RZ^(2)[(1)/(n_(f)^(2))-(1)/(n_(i)^(2))]`
R and `(1)/(n_(f)^(2))-(1)/(n_(f)^(2))` are constant
`:.(1)/(lamda)propZ^(2)`
and Z = 3 is maximum for doubly ionized lithium in a given atom.
