uses of helium

Helium is a chemical element with a symbol and an atomic number of two. It is colorless, odorless, odorless, non-toxic and inert gas. In addition, uses of helium include intermediate, cooling, and inflatable car balloons. There is also the formula and properties of helium.

Helium is still an inert gas element in group 18 of the periodic table. It is the second element after hydrogen, colorless, odorless, and tasteless. Compared with the remaining elements, natural atmospheric pressure and a temperature of about 272 ° C can be converted to a solid-state, which is characterized by low boiling and freezing points.

Found out
It was discovered by French scientist Pierre Janssen in 1868. Accompanying this discovery was the existence of helium on the surface of the sun rather than on the earth, but he did not realize what this particular element was, and then conducted continuous research on them He finally reached Sir William Ramsay in 1895, and at the same time confirmed his identity. Niels Langlet and Tudor Cliff reached the same conclusion.

This is why no known compound contains helium, because it is a gaseous element, and because its air content does not exceed 0.0005%, it escapes from space far from the atmosphere. The gravity of the earth is not controlled by a helium deficiency, which can be compensated by the decomposition of radioactive elements in the crust. The alpha molecules produced by the decomposition of these elements combine with two electrons and form helium again ...
