Noble Gases
The Noble Gases are the far right elements on the periodic table. On the earth they are scarce so we don¹t see much of them. They are do not react well with anything. In fact until around the 50¹s they hadn¹t found anything that they would react with any of the gases. But then someone found out that Fluorine one the of most reactive elements could form compounds with Xenon. Later they found that it could react with most of the other nobles.
Helium is one of the more scarce nobles on earth but in the universe it makes up 25% of it. Helium¹s presence was discovered by using spectral analysis to detect helium in the sun¹s spectrum. Helium is not found a lot on the earth because gravity cannot keep helium from escaping to space. Helium is found mostly in stars, where it goes through nuclear fusion with hydrogen. Most Helium comes from natural gas taps in North America. It is used in balloons and divers use it with oxygen to breath easier and to not get sick or dizzy.
Neon is an element that is lighter than air. The element is found most common in the atmosphere of the earth. It is also found in the earth¹s crust. It was discovered in 1898 by Sir Walter Ramsey and Morris W. Travers. Its uses include electric signs,lamps,and lasers.
Argon is the most abundant and most used noble on earth. It was discovered by Lord Rayleigh and by Sir Walter Ramsey in 1894. Argon makes up about 1.2 % of the earths atmosphere. It is found naturally in rock and in the air. It is used for electric light bulbs and floursent tubes. It is also used a lot in industry.

I think this can use some more detail. Your sentence structure also seems kind of repetitive. Next time maybe you can try using more variety in your sentence structure?
