Question

The spectrum of helium is expected to be similar to that of (A) H (B) Na (C) Li+ (D) He+

Tardigrade Admin · Accepted Answer

The spectrum of an atom depends on the number of electrons present in it. Here, helium has two electrons, so the spectrum of Li+(Z=3) is similar to that of helium because both He and Li + have two electrons.
