why does helium have more spectral lines than hydrogen?

Spectral Lines of Hydrogen, Helium, Mercury Vapor and Neon

It has more lines in it compared to hydrogen emission spectrum. It is mainly because the helium atom has more electrons than a hydrogen atom. Therefore, more electrons get excited when we pass a white light beam through a helium sample, and it causes the emission of more spectral lines.
