Helium is the least dense, or lightest gas in the world. It can be used to float airships. Most amusement parks use helium to float balloons to sell to kids. It is not harmful of course!

What quality of helium makes it useful?
Helium is lighter than air (which means it can be used to make stuff float, like balloons) and a noble gas (which means that it won't react with other elements). Both of these qualities make helium very useful.
How much helium is in a helium tank?
The amount of helium in a tank depends on how big the tank is (volume), the pressure of the helium and its temperature. It is calculated from the ideal gas equation with allowance for compressibility.
When was helium first isolated?
Because it is inert, liquefied helium has a number of applications. It is used in cryogenics to freeze biological materials for long-term storage and later use (24%). It is also used in welding and to create controlled atmospheres. It is used to detect leaks in pipes. Its inert nature makes helium useful for cooling nuclear power plants. Since helium molecules are so small, mixtures of helium and have proven to be useful in treating people with severe asthma or lung problems. It is also mixed with oxygen for use in deep-sea diving. Most people are certainly familiar with the use of helium as a lighter-than-air substance. It holds up our birthday balloons. The motorized blimps that hover over sports stadiums are held up by helium. They are, in reality, very large balloons. see related link
What is one use of the noble gas that relies on the fact that it is unreactive?
Noble Gases are useful because they make up chemical elements.
What is helium made from?
Do you mean helium? Helium is an element, so it's made of .... helium!
How useful is helium?
How Helium is used: It is used to blow up balloons.

Why is argon useful?
Because it is inert but unlike Helium is slightly Heavier than air.
How much helium is in a helium tank?
The amount of helium in a tank depends on how big the tank is (volume), the pressure of the helium and its temperature. It is calculated from the ideal gas equation with allowance for compressibility.
Are any of the isotopes of helium useful to humans?
Helium-3 is used in experiments for nuclear fusion, neutron detection, cryogeny installations and RMN for medical use.
Does the moon have any resources?
The Moon has a gas called Helium 3, which is useful for Nuclear Fusion.
Is helium good for the environment?
Firstly, helium is NON- TOXIC. Helium is useful to mankind as it is used in cryogenics, deep-sea breathing systems, blowing up balloons, providing the lightweight in airships etc. Breathing in a small amount of helium will temporarily increase the pitch of your voice (no harm), however, excessive inhaling of helium is dangerous as it may cause death by asphyxiation within minutes!
What properties make helium useful?
While it is not a "Noble Gas" it is much lighter than air. It is not lighter than Hydrogen, but it does not ignite as easily.

What are The advantages and disadvantages of helium in airships?
First of all, there isn't much choice. To get the airship to lift, one has to use a gas that's lighter than air. Only two do that well enough to be useful, hydrogen and helium. Hydrogen is lighter and cheaper, but horribly flammable. Helium is more expensive, provide less lift, but is entirely non flammable.
What is the element name for He?
Helium Helium
What is one use of the noble gas that relies on the fact that it is unreactive?
Noble Gases are useful because they make up chemical elements.
