The correct answer is helium.

Alissa · Answer 2

For Neon (Ne), the atomic mass is 10 daltons, so the molar mass is 10

grams. This means that one mole (Avogadro's number of particles, 6.02

x 10^23) has a mass of 10 grams. Hydrogen, with an atomic mass of

1 dalton for it's single proton, the molar mass would be 1 gram. With

Neon, the speed of the individual Neon atoms is

proportional to 1 / sqrt (10). So it is helium.
