Helium is denser than hydrogen because as the molecular or Atomic Mass of a gas increases, density increases as well.
Hydrogen has a molecular gas of about 2 g/mol while helium has an atomic mass of about 4 g/mol.
What else can I help you with?
The density of hydrogen is lower than air and can be used to fill balloonswhy is helium used instead of hydrogen?
Helium is used instead of hydrogen in balloons because it is non-flammable, while hydrogen is highly flammable. This makes helium a safer option for filling balloons to prevent any potential fire hazards. Additionally, helium is also lighter than air, allowing balloons to float easily.
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
When are hydrogen and helium form?
Hydrogen and helium are formed in Sun.
What makes helium float?
Helium-filled objects "float" in most substances that aren't primarily hydrogen or helium because of it's less dense. Helium has a weight of 0.1785 grams per liter. Nitrogen, on the other hand, which makes up 80% of the air we breathe, weighs 1.2506 grams per liter. Things that are lighter over the same surface area are more buoyant.However, helium isn't the lightest element. Hydrogen, weighing a mere 0.08988 grams per liter, is. The reason hydrogen isn't used as commonly as helium to fill things is because of the high flammability of hydrogen, with a small spark causing a hypothetical hydrogen balloon to explode.
In what layer are light gases such as helium and hydrogen found?
Light gases such as helium and hydrogen are found in the exosphere layer of the Earth's atmosphere. The exosphere is the outermost layer and consists of very low-density gases that extend out into space.
Is hydrogen lighter than helium?
No, helium is almost 4 times as heavy as hydrogen.
Would a helium balloon float on a planet made of hydrogen?
No, because the density oh helium is bigger (x 10).
Why is density of hydrogen lower than air and can be used to fill balloons why is helium used instead oh hydogen?
Because helium is lighter
Is a canster of air lighter than a canster of helium?
No, helium has the second lowest density out of all the elements and with Hydrogen having the smallest density but it not being in the air it means the canister of air is heavier.

What liquid has lowest density?
kerosene
What are the symbols for hydrogen and helium?
The symbol for hydrogen is H, and the symbol for helium is He.
What are the two main elements found in the stars?
Hydrogen and helium
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
Hydrogen and helium formulas?
Hydrogen is H2. Helium is He.
Does helium have hydrogen in it?
No. Helium and Hydrogen are two different elements.
When are hydrogen and helium form?
Hydrogen and helium are formed in Sun.
