Find out applications of all the inert gases, prepare a chart and display it in the class
Answers
Explanation:
The noble gases, also recognized as inert gases and aerogens, are the elements of the modern periodic table in group 18. The following are the members that are identified as Nobel gases.
Helium (He)
Neon (Ne)
Argon (Ar)
Krypton (Kr)
Xenon (Xe)
Radon (Rn)
The outermost shell of the Nobel gases are completely filled, so they are inert in nature having the general formula of electronic configuration ns2 np6. The noble gases are monatomic gases as they are unreactive in nature that is a property of these gases. The combination of two terms mono and atomic implies a single atom is monatomic.
Uses of Noble
In metallurgical processes, argon is widely used in order to provide the necessary inert atmosphere. This inert atmosphere plays an important role in welding titanium, aluminium, stainless steel, and magnesium. It is also used in the production of titanium. Also limited amount of argon is used in germanium and silicon crystals which are used in electric light bulbs, transistors, etc.
Helium is used in nuclear reactors as a cooling gas and used as a flow-gas in liquid-gas chromatography. It finds its application in airships and helium balloons.
Helium balloons are used to check the weather of a particular region. Helium is preferred over hydrogen though hydrogen is cheaper, as helium is readily available and hydrogen is highly inflammable. Hence, due to safety issues helium is preferred in aircraft.
It is used by divers to dilute oxygen over nitrogen in the gas cylinders used by them as nitrogen can easily be dissolved in the blood which results in a painful condition called bends. The risk of helium causing bends is slightly lower than nitrogen.
Neon is used in discharge tubes which is the reason behind the reddish-orange glow produced by neon lights.
Xenon and krypton find their application in photographic flash units due to the generation of very bright light. It is also used in lighthouses.
Neon, xenon, and krypton are used to produce different colour lights.
