YES ! see Periodic Table for more info
What else can I help you with?
Is there anything lighter than oxygen?
In fact there are seven elements lighter than oxygen: hydrogen, helium, lithium, beryllium, boron, carbon and nitrogen.
Which is lighter - helium or hydrogen?
Helium is lighter than hydrogen. Helium has an atomic number of 2, which means it has two protons and two neutrons in its nucleus, making it lighter than hydrogen, which has only one proton in its nucleus.
How much lighter is hydrogen compared to helium?
Hydrogen is about 7 lighter than helium.
Which gas is lighter than helium?
hydrogen
Would an hydrogen balloon float better than a helium one?
Hydrogen is lighter than helium. So hydrogen balloon will float better than helium.
Is hydrogen lighter than helium?
No, helium is almost 4 times as heavy as hydrogen.
Is helium lighter than air?
Yes, helium is lighter than air. Helium is a lighter-than-air gas that has a lower density compared to the gases that make up our atmosphere, such as nitrogen and oxygen. This is why helium-filled balloons float in the air.
What is lighter than helium but heavier than air?
hydrogen
Whatgas is lighter than air?
Hydrogen and Helium.
Is hydrogen more dangerous than oxygen Why?
Hydrogen is dangerous than Helium because Hydrogen is a stronger gas than Helium.
What element is lighter than air?
There are many, but one is Helium
Why is helium used to fill balloons instead of oxygen or hydrogen?
Helium will not burn. Hydrogen burns in air to form H2O (water) Thus in circumstances where a lite gas is required (e.g. in a balloon) it is safer to use Helium. see http://www.unmuseum.org/hindenburg.htm
