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.
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.
Helium is lighter (less dense) than oxygen & nitrogen.
Hydrogen and helium are formed in Sun.
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.
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.
No, helium is almost 4 times as heavy as hydrogen.
No, because the density oh helium is bigger (x 10).
Because helium is lighter
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.
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.
