The electronic transition from

n=2

n=1

will produce the shortest wavelength in (where,

n=

principal quantum number)

View answer and explanation

Correct option: D

\mathrm{Li}^{2+}

Option D (Li²⁺) is correct because the shortest wavelength corresponds to the largest energy transition, which is proportional to Z² (atomic number squared).
