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.

Is gravity an element?
Yes, Gas does have a gravity. Gravity affects anything and everything that has a mass. But as the gravitational force is directly proportional to the mass, and since gases have a very very low mass, The force exists but is very low. If gases were not affected by gravity, the atmosphere would not exist!
Can an object have more than one center of gravity?
No, objects cannot have more than one center of gravity. The center of gravity of an object can however change.
What does weight have to do with matter?
Matter is what is in an object...it is what something is made of.Weight is the effect of gravity on an object.The more matter in an object, the greater effect gravity has on that object, making it weigh more than another object with less matter.Don't forget that size does not always show how heavy something is...If you have a small object which is really dense (contains a lot of matter), it may weight more than a larger object with a low density.
How does a balloon rise against gravity?
A balloon is filled with helium, which is less dense than the air around us. Because of this, it is able to float. But, over time, the helium leaves the balloon making it fall again.
Do small objects have more or less gravity than large objects?
The gravity depends on the mass.
Which pulls with greater force on the earth's oceans the sun or the moon?
The gravity from the Sun is more than the gravity from the Moon. However, the Moon has a greater effect on the tides.The gravity from the Sun is more than the gravity from the Moon.

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
What has more mass hydrogen or helium?
Helium has more mass than hydrogen.
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 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.
What is The moon has more gravity than the earth.?
"The moon has more gravity than the earth." is a question (about the moon and gravity).
Why do the Moon's gravity have a greater effect on earths ocean tides than the suns gravity?
Even though the suns gravitational pull is stronger than the moons and does infact effect the tides slightly, the moon is close enough to pull the tides more than the sun. Its all distance related.
How does helium lift a balloon?
This lifting force comes from helium weighing less than air, resulting in an effect known as displacement. Because the surrounding air has been displaced by a substance with less weight per unit of volume, it is pushed away (upward, thanks to gravity) by the heavier substance.
Does the sun have less gravity than the earth and moon?
No. The sun's gravity is much stronger than that of Earth or the moon. However, its effect on the tides is less than that of the moon because it is much farther away. Tidal forces diminish with distance more quickly than the force exerted by gravity.
What has the most gravity?
In general, the thing that has the most mass has the most gravity. Mass and gravity are directly proportional. It's that simple. Gravity could be said to be a function of mass. Think about a few things and the mass and gravity associated with them. A truck has more gravity than a person, who will have more gravity than a mouse. A skyscraper has more gravity than any truck, and the moon has more gravity than any building. The earth has more gravity than the moon, and Neptune has more gravity than earth. Jupiter has more gravity than Saturn, which has more gravity than Neptune. The sun has more still than Jupiter. The sun has more mass than all the planets put together, in fact. And then some! There are many stars with a greater mass (and therefore greater gravity) than the sun, and black holes have enormous gravity that can easily exceed that of stars. Then there's something called a super-massive black hole, which has a really, really, really large amount of gravity.
