Argon is the third noble gas, in period 8, and it makes up about 1% of the Earth's atmosphere.

Argon has approximately the same solubility as oxygen and it is 2.5 times as soluble in water as nitrogen .

This restriction extends to animals that consume seafood in their diet.

Argon was suspected to be present in air by Henry Cavendish in 1785 but wasn't discovered until 1894 by Lord Rayleigh and Sir William Ramsay.

World production exceeds 750.000 tonnes per year, the supply is virtually inexhaustible.

Argon does not react with the filament in a lightbulb even under high temperatures, so is used in lighting and in other cases where diatomic nitrogen is an unsuitable (semi-)inert gas.

The amount of the isotope in the object is compared to the amount of the isotope's decay products.

The object's approximate age can then be figured out using the known rate of decay of the isotope.

This chemically inert element is colorless and odorless in both its liquid and gaseous forms. This gas is isolated through liquid air fractionation since the atmosphere contains only 0.94% argon.
