In the following atoms and moleculates for the transition from n= 2 to n = 1, the spectral line of minimum wavelength will be produced by |
Hydrogen atom Deuterium atom Uni-ionized helium di-ionized lithium |
di-ionized lithium |
$\frac{1}{\lambda}=R Z^2\left(\frac{1}{1^2}-\frac{1}{2^2}\right)$ For di-ionised lithium the value of Z is maximum. |
