Because it has mass. It may be lighter THAN AIR, but that does not mean it is weightless. Even cells have weight.

How can you make your voice funny?
Try sucking in helium found most commonly in balloons. Only the balloons that need a weight to keep them down have helium in them - because helium is lighter than air. Anyway helium will make your voice sound high- pitched therefore making your voice sound funny. Helium in big intakes can damage your lungs; but don't worry you would have to suck in a lot to damage them.
What is the element name for He?
Helium Helium
What element has 2 protons 1 neutron and 2 electrons?
Helium has 2 protons, 2 neutrons and 2 electrons. The symbol for helium is He and the atomic number is 2.
What is the valency of helium?
The valency of Helium is 0
Is a helium a metal or nonmetal?
Helium is a nonmetal. Think about the helium balloon!
What is the helium weight?
Helium's atomic weight = 4 amu
What is the atomic weight of Helium atom?
Helium atom has 2 protons and 2 neutrons (that accounts for its atomic weight). The atomic weight of helium is 4.00260
What is the chemical mass for helium?
The atomic weight of helium is 4,002602(2).
What is atomic weight of helium?
4.002602 g/mol
Is a lead atom heavier than a helium atom?
Yes; helium has an atomic weight of 4.00260, and lead has an atomic weight of 207.2.
Do helium or argon gases move faster?
At the same temperature, helium gas will move faster due to its lower atomic weight. Helium has an atomic weight of 4g/ mol, while argon has an atomic weight of 39.95g/ mol.
How do you convert 26.7kg of helium into moles of helium?
6675 moles Moles = weight (in g) / atomic weight = 26700 g / 4 = 6675 moles
Can you combine aluminum with helium to get a light weight metal?
No. helium does not react with any other element
A helium balloon contains 0.46 g of helium how many moles of helium does it contain?
0.46 divided by the formula weight of helium (4) 0.46/4=0.115 or 0.12 moles of Helium
Is a tank of helium lighter than a empty tank?
No, helium has weight, but it rises when its in an expandable container such as a balloon because it is lighter than the nitrogen rich atmosphere but inside of a rigid container the helium can only add weight. (see the mythbuster's episode about the helium football)
Why doesn't the helium bottle float away?
because of the weight of the bottle, also the helium may be compressed
How much does a small helium balloon weigh?
* Calculate the volume of the ballon * Calculate the weight of the helium: G= V x 0,1786 (the helium density in g/L) * Add the weight of the balloon material (rubber, plastic, etc.)
