Yes, hydrogen is the least dense of all known elements. I beleive helium is about .6 the density of air, while hydrogen is about .2 or .3

Anyhow, thank for backing me up here.

EDIT: I am a stupid chemist Read below if you want some decent information. Mine were estimates, and they were wrong. Thanks fvp_gtho
