Noble+Gases

**Noble Gases -Carlos**
Noble Gases are a group of chemical elements that have similar properties such as, being odourless, colourless and monatomic gases (gases with atoms that do not bound to each other) with a very low chemical reactivity. There are six noble gases that occur naturally, they are Helium (HE), Neon (NE), Argon (AR), Krypton (KR), Xenon (XE) and radioactive radon (RN). The noble gases are exactly the members of group 18 of the periodic table. 

‍‍What applications use Noble Gases? ‍‍ -Carlos
As we all know, elements of the periodic table serve a purpose when it comes to machinery, resources, tools, technology and much more. Helium is one of the popular elements in the Noble Gases group; it is used in Party Balloons, Weather Balloons, Breathing Gas mixtures, MRI scanners, Welding and Refining and more. "Helium is seven times less dense than air, so a balloon floats upwards if filled with helium, they could use hydrogen but unlike helium it is highly flammable. It is used in diving masks neutralize the pressure as the divers descends into the sea. MRI scanners need very powerful magnetic fields, providing by superconducting magnets. Metals only become superconductors with absolutely no resistance and at a very lower temperature. Liquid helium is the coldest liquids and boils at just -268.9 degrees; it can be used to cool the coil of the magnets. Welding and refining requires the use helium and argon (another gas from the noble gases group) to create an inert shield during the wielding. This prevents hot metal oxidising (losing electrons) and weakening the weld. These are some of the applications which use Noble Gases"-( []).

Trends in behaviour and Element Structures/Compound form -Dimitri
The ways in which Noble gases behave are influenced by three factors which are diffusion, partition and nuclear transformation. Diffusion is when gases move from areas of higher concentration to lower concentration areas until balance is reached. Partitioning describes the relationship between water and the atmosphere, in this relationships are equal. They generally do not react with other elements to form compounds. However there are a few compounds that involve such as [|tetroxide]  (XeO4) and sodium perxenate (Na4XeO6).
