Element number one, is in the group other non-metals (alongside C, N, O, P, S, Se), has an atomic weight of 1.00974 amu, a hexagonal crystal structure, and a atomic radius of 53 picometers (pm). It is found the Sun, and was once used in blimps, before helium as used.
The people who inflate the blimps knew hydrogen (H) is reactive, so they went helium (He) for blimps, which is non-flammable.
