Helium
Hydrogen is the lightest element on the periodic table. Henry Cavendish collected Hydrogen by placing Zinc in an acid and originally called it inflammable air. However, Paracelsus of Switzerland had noticed 250 years before that Iron placed in acid gave off a gas and that gas would burn: but did not study it further.
Hydrogen is a gas, a non-metal, it is the lightest element.
The lightest non-flammable gas is Helium.Note: After Helium, Nitrogen technically comes next however it can burn at a very high temperature. Because of this, Neon would be the next lightest truly non-flammable gas.
Hydrogen was, and is, the lightest gas
The old name of hydrogen gas is "inflammable air."
Hydrogen is the lightest gas.
the simplest element. Hydrogen is a gas, a non-metal, it is the lightest element.
The highly inflammable gas in LPG (liquefied petroleum gas) is propane.
The lightest 'non-metal' could be Hydrogen and Helium! Both are gases, and therefore, not a metal.
Yes it is, and it's also the lightest gas in the universe.
Many (though not all) metals will dissolve in sulfuric acid. The colorless inflammable gas that is produced is hydrogen.
gas is the lightest in weight
