What is Argon?
Argon is a chemical element in the eighteen group of the periodic table. It is a noble gas, and it is the third most abundant gas in earth’s atmosphere.
Argon is the most common gas in the atmosphere besides Nitrogen and Oxygen. Argon is a noble gas (like helium) which means that it is completely inert.
Properties Of Argon
- It is odourless, colourless gas that is totally inert into other substance.
- Under extreme conditions, argon can form certain compounds even though it is a gas.
- It is characterized by same solubility level in water as that of oxygen.
- It has low thermal conductivity.
