I'm fairly certain that both hydrogen and helium are lighter then air. Example, if you filled a balloon with either the balloon would float.
And both are combustible.
Hydrogen is some what more dramatic in its combustion however, the tragic example being the hindenburg.
The symbol for hydrogen is H, and the symbol for helium is He.
Hydrogen and helium
Hydrogen is H2. Helium is He.
Hydrogen and helium are formed in Sun.
No. Helium and Hydrogen are two different elements.
No, helium is almost 4 times as heavy as hydrogen.
About 96% is hydrogen, about 3% helium.
helium
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
Helium has more mass than hydrogen. Helium is composed of two protons and two neutrons, while hydrogen is a single proton.
Chemical symbol (not formula) of hydrogen is H and for helium is He.
All stars contain hydrogen and helium.
