First of all the question is erred, helium is part of what is commonly called air. Air is in fact a composition of all the gases and substances that combine together to form the atmosphere within the boundaries of the earth's gravitational field. Helium being the second lightest of the elements composing the Periodic Table has an atomic weight of 4.002602, nearly 4 times the weight of hydrogen (1.00794), but more than one third the weight of nitrogen (14.00674) and nearly one quarter that of oxygen (15.9994).
Nitrogen 78 % is the most abundant gas
Oxygen 21 %
Argon .934 %
The aforementioned are the "major gases".
The remainder are the "noble gases", including:
Helium (He) .000524 %
Carbon Dioxide (CO2) .0387 %
Neon (Ne) .00181818 %
Methane (CH4) .000179 %
Krypton (Kr) .000114 % (Nothing to do with Superman, Except that
the creators of superman borrowed the name of the element)
Nitrous Oxide (N2O), Nitrogen Diode (NO2), Xenon (Xe), Hydrogen (H), Ozone (O3), Iodine (I), Carbon Monoxide (CO), Ammonia (NH3).
In the lower atmosphere is Water Vapor (H2O), better known as relative Humidity and Rain, which is in concentrations of 1 % to 4 % at surface level.
Water or H2O would have an atomic weight derived from its combined values of 2 Hydrogen atoms and 1 Oxygen atom:
1.00794
1.00794
+ 15.9994
------------------
18.00988
This value is clearly less than that of Neon but since H2O readily bonds with other H2O molecules it becomes heavier and thus sinks to the bottom of our atmosphere.
In case you are completely unaware of the difference of elements and molecules, elements are the most fundamental building blocks of all matter, whereas molecules are the combination of elements in the creation of all other matter or compounds.
In summary Helium is lighter. Just as a beach ball is a thin polypropylene film filled with air (atmosphere) and floats readily on water, A Basketball is heavier (comprised of rubber, or synthetic substance, and leather, filled again with air (atmosphere) and thus floats deeper in the water as does the beach ball.
What else can I help you with?
How does helium defy gravity?
Helium defies gravity because it is lighter than the air around it. This causes it to rise upwards, creating a buoyant force that opposes gravity. This is why helium balloons float in the air.
Why does helium defy gravity?
Helium defies gravity because it is lighter than the surrounding air. This causes it to rise and float upwards, rather than being pulled down by gravity like heavier objects.
If gravity is always pulling things down how does helium rise?
In a vacuum, a balloon with helium (for example) would also fall down. The point is that gravity pulls on the surrounding air with more force, because it is heavier; this pushes the balloon up. The situation is similar to a boat floating in water. The water displaces the boat - pushing it up precisely because of gravity.
Does gravity force a hellium balloon to rise?
No, not directly ... it needs gravity to be present, but gravity alone won't do it. There's plenty of gravity on the moon, but a helium balloon won't rise there. A helium balloon floats in air, for exactly the same reason that a block of wood floats in water. Look up "Archimedes' Principle" and read about it.
What is the difference in lifting power between hydrogen and helium?
Hydrogen has more lifting power than helium because it is lighter. This means that a given volume of hydrogen can lift more weight than the same volume of helium.

What is heliums specific gravity?
helium doesn't have a specific gravity
Why do balloons filled with helium gas rise to the sky?
Hydrogen is lighter than air, so the force of gravity is overcome by the force of the heavier air pushing on the balloon. Same as why bubbles float to the top of water. When balloon is filled with air there is no competing force so gravity takes over and pulls the balloon down.
How does the gravity of the planets effect the mass?
the bigger the planet the more gravity it has because it needs to hold it self together so it has more gravity than smaller planets who require a small amount of gravity to hold themselves toghther
Why do you feel the Moon's gravity more than the sun's gravity?
Despite being extremely more massive than the Moon, the Sun is so far away that its gravitational effect on us is actually smaller than that of the Moon. Gravitational effect is directly proportional to the amount of mass, but proportional to square of the distance. This means that distance is more important than mass in figuring out gravity, so the Moon's proximity becomes more dominant than the Sun's massive size.

What has more mass hydrogen or helium?
Helium has more mass than hydrogen. Helium is composed of two protons and two neutrons, while hydrogen is a single proton.

What is more dense helium gas or air?
air is more dense than helium
If gravity is always an attractive force between two objects why does a helium balloon fall up?
This is a really good question! Helium balloons 'fall' up because helium is lighter than air. In other words, even though gravity is pulling the balloon down, the helium is so light the balloon rises.
