Elements of group 18 are all gases and have completely filled outermost orbital that’s why these elements are highly stable and don’t react with other elements easily. This is the reason these elements are known as inert gases or inert elements. The word inert means chemically unreactive. These gases are also known as Noble Gases. Group 18 is also called zero group. So, elements of group 18 are also called zero group elements.
Here we are providing list of Inert Gases with their electronic configuration –
Noble gas Helium was discovered by Pierre Janssen and Joseph Norman Lockyer. Noble gas Radon was discovered by Friedrich Ernst Dorn while remaining four noble gases Neon, Argon, Krypton and Xenon were discovered by Sir William Ramsay. He was awarded the Nobel Prize of Chemistry in 1904 for his achievements.
There are numerous uses of inert gases or noble gases in various fields specially in the field of metallurgy. Here we are listing few applications of each inert gas separately in many fields –
Helium is used for the treatment of asthma, emphysema and other breathing problems.
Helium is used in balloons.
Helium is used in welding.
Helium is used in industries for preventing explosions.
Helium is used for cryogenics.
Liquid Helium is used for magnetic resonance imaging.
Helium is used in semiconductor processing.
Helium is used in laser processing as well.
We used to use Neon in television tubes.
Neon is also used in cryogenics.
Neon is used in sign boards as on passing electricity it glows brightly.
Neon is used in lasers.
