Argon is the 3rd noble gas, in period 8(p-block) of Periodic table, it makes up about 1 per cent of the Earth's atmosphere.
The solubility of Argon is approximately the same solubility as oxygen has. It is 2.5 times as soluble as nitrogen in water. The name "argon" is derived from the Greek word ?Ïγ?ν, meaning "lazy" or "inactive".

History of argon gas

In 1785, Argon was suspected to be the component of air by Henry Cavendish.

But in 1894, Argon was first isolated from air at London University College, by William Ramsay and Rayleigh by detaching carbon dioxide, oxygen water and nitrogen from a sample of air.

Properties of argon gas

Argon is an element with symbol Ar and with atomic number as 18.

Argon is colourless, odourless, non-flammable and non-toxic in both gaseous and liquid form.

Argon is inert under majority of conditions and at room temperature it forms no stable compounds.

It has an atomic mass of 39.948 g/mol and its density is 1.78.10-3 g/cm3 at 0 degree Celsius.

It has melting point of -189 degree Celsius and boiling point as -185.7 degree Celsius.

It has 6 isotopes and its vanderwaals radius is 0.192 nm.
