The existence of Argon was suspected by Henry Cavendish but it was not until more than a hundred years later that it was isolated. Lord Rayleigh and Sir William Ramsay conducted an experiment in which they removed all the oxygen, carbon dioxide, water and nitrogen from a sample of clean air.
They found that nitrogen obtained in this manner was 0.5% heavier than that obtained from other compounds. They concluded that that there was some other gas mixed in with the nitrogen. It was Argon.
In nature, Argon is a gas
Earth's atmosphere.
Divide 40g by the mass of one atom to find the number of argon atoms.
Check E.Merk or BDH etc.
in the air it makes up about some of the earth's atmosphere
Argon is chemically inert, it does not combine with other elements. So there wont be any items at home made from argon, except for the neon lights. Neon lights when mixed with argon produces different colour depending on the ratio of each.
the equation is Xg multiplied by the moles/grams of X = moles of X (the grams cancel leaving you with moles) 607g Ar x 1 mole/ 39.95g = 15.19 moles
Ar is the chemical symbol for argon.
Search in the web to find the answer =) =P
Argon is an element and all the atoms in argon are argon atoms.
argon
It is not easy to find because it is so inert. It does not react with almost any substance.
