What is the lighter element hydrogen or helium?
Hydrogen. It's first on the periodic table, with usually a sigle proton, and an atomic weight of 1.00794.
What are the symbols for hydrogen and helium?
The symbol for hydrogen is H, and the symbol for helium is He.
Why is helium lighter than nitrogen?
Your question is wrong because hydrogen is the lightest gas but other than that its the lightest nobel gas, and that's just cause its atoms don't have much to them, and neither dose its molecules. With an atomic mass of 2, its the second lightest substance there is, and therefore attracted by gravity the second least of anything, so its gonna be ontop of all other matter (exept hydrogen which has the atomic mass of one)
What is colder helium or hydrogen?
Liquid Helium is colder than Liquid Hydrogen.
Why helium is used in weather balloons rather than hydrogen?
Because of an accident that happened. A weather balloon was filled with hydrogen and when lightning hit it, it set on fire. Hydrogen is flammable, so they use Helium instead, because Helium is a nobel gas and so isn't flammable, but also lighter than air so the balloon floats.
How much lighter is hydrogen compared to helium?
Hydrogen is about 7 lighter than helium.
Is hydrogen lighter than helium?
No, helium is almost 4 times as heavy as hydrogen.
Which gas is lighter than helium?
hydrogen
What is the lighter element hydrogen or helium?
Hydrogen. It's first on the periodic table, with usually a sigle proton, and an atomic weight of 1.00794.
Whatgas is lighter than air?
Hydrogen and Helium.
Would an hydrogen balloon float better than a helium one?
Hydrogen is lighter than helium. So hydrogen balloon will float better than helium.
What is the difference between hydroge and helium?
Helium is the lighter gas but hydrogen is very flammable
Is hydrogen or helium safer to use?
Generally speaking, helium is safer, as it is an inert gas, but Hydrogen is cheaper to make and is lighter.
What is lighter than helium but heavier than air?
hydrogen
what is Helium about?
helium is after haydrogen it means hygrogen is lighter than helium. now the question arises that "Q.1"why we use helium instead of hydrogen coz hydrogen is lighter than helium. Ans.1:hydrogen has 1 electron in its 1st shell and helium has it's complete shell with two electron. When we fill hydrogen in the baloon they form ionic bond... so it is used double...
What element is lighter than air?
There are many, but one is Helium
What type of element is better than helium?
In terms of buoyancy, hydrogen is better than helium because it is lighter. However, hydrogen is flammable, so helium is typically preferred for safety reasons.
