Learn about Three Noble Gasses

By Ali Knowles and Raven Langley


Ne, or 'Neon'!

Its atomic number is 10

The atomic symbol is 'Ne'

Neon's atomic mass is 2

William Ramsay discovered Neon in 1898 at a University in London.

Neon can be found partially in the atmosphere, at it is very rare.

While some elements are interesting to look at, Neon is not. Neon is colorless, tasteless, and odorless.

Neon is most commonly referred to as the extravagant light up signs that one will often see in the windows of bakery's, shops, and more. A stereotypical light up neon sign will say, "open" or "closed".

While Neon possesses multiple isotopes, it only possesses three stable isotopes: 20Ne, 21Ne, and 22Ne.

Basic Facts About Helium

He, or 'Helium'!

The atomic number of helium is 2

Helium's atomic symbol is 'He'

It's atomic mass is 4

Pierre Janssen, a French astronomer, discovered Helium in 1868 during a solar eclipse in Guntur, India

Helium can be found in the ground as a source of natural gas.

Helium cannot be seen, smelt, or tasted- but when put in a balloon, helium will make it float.

Helium has two isotopes, although it is almost all made up of He-4.

The uses for Helium are various; Helium gas can be used for multiple types of balloons, both scientific and party balloons. Helium can also be used to fill and inflate blimps.

Basic facts about Argon

Ar, or 'Argon'

The atomic number of Argon is 18

Argon's atomic symbol is "18"

The atomic mass is 39.948 amu

It was discovered in 1894 by Sir William Ramsay

It can be found in the air

It is a Colorless gas

Argon is in lightning

Isotopes: Ar-40 and Ar-38 are used in the production of radioisotopes. Ar-41 used to trace gas flows.
