molecule is lighter than hydrogen.....................
Hydrogen molecule is the lightest because of its atomic mass being less than any other molecule .i.e 1amu (atomic mass unit). Hence Hydrogen molecule is lighter than Methane molecule.
This gas is hydrogen (H) and has a diatomic molecule.
Hydrogen is the lightest gas.
Hydrogen is the lightest element. The isotope protium is the lightest kind of hydrogen atom.
hydrogen is the lightest element
Protium (Hydrogen-1) is the lightest and by far the most common isotope of hydrogen.
the lightest elements are gases and the lightest of these are hydrogen and helium.
hydrogen
No hydrogen is the lightest element.
Hydrogen was, and is, the lightest gas
In terms of mass from lightest to heaviest, the order is: proton, hydrogen molecule (H₂), glucose, hemoglobin, and then methanedust particle. A proton is the fundamental unit of hydrogen, while H₂ is a diatomic molecule consisting of two protons. Glucose (C₆H₁₂O₆) is significantly heavier than both hydrogen and its molecule, and hemoglobin, a complex protein, is heavier still. Methanedust particles, which can vary in composition, are typically the heaviest in this list.
The lightest element of all should have the lightest atomic mass. It is hydrogen-1 isotope. This atom has only one proton and no neutrons.
