Concept in Definition ABC

The helium it's a chemical element that as such occupies a place within the Periodic table, which precisely groups all these elements. Between his traits singular are told that it has a atomic number number 2 and it is symbolized through the words I have.

It is considered an element inertIn other words, it is lifeless, gaseous, because it has the properties of a gas, it is colorless, that is, it has no color, no smell or taste.

After item chemical Hydrogen, helium, is the other element lighter found on the planet. Another essential feature is that it has the lowest boiling point.

The discovery of Helium dates back to the second half of the 19th century and we should actually say that its ID and denomination is shared by two astronomers, one of French nationality and the other a native of the United Kingdom. First, Jules janssen, he appreciated it in the contemplation of a eclipse, like a yellow streak across the sky. He only recorded such observation. Meanwhile, the English

Norman lockyer, who was observing the same eclipse, went a little further, and identified it as a new chemical element and called it helium.

Now, having mentioned its physical and particular characteristics and its origin, we must say that the Helium is a hyper element used in the world and in various fields such as industry and science. MRI scanners or airships that fly the skies are moved by helium.

Also, helium is widely used to inflate balloons, yes, those typical of children's parties and events. We can inflate them with our own airHowever, those balloons that have been inflated through helium can stay in the air even if one lets them loose. For this reason, when balloons are released, they are inflated through this medium.

A curious and funny question around this element is that if a person inhales helium when he speaks, his voice will come out finite, finite, until the helium completely leaves his body.
