argon
An inert, nontoxic gas used in insulating windows to reduce heat transfer
a chemical element (symbol Ar) with an atomic number of 18
so named on account of its inertness by Rayleigh and Ramsay, who prepared and examined it in 1894-95
A colorless, odorless gas occurring in the air of which it constitutes 0
{i} gaseous chemical element found in air and volcanic gases
A colorless, ordorless inert gas that is the third most abundant consituent of dry air It comprises 0 93%
93 per cent by volume, in volcanic gases, etc
Argon, #18 on the periodic table, is colorless and odorless, like all of the noble gases It has an atomic mass of 39 948 amu, and its electron levels are 2-8-8 Ar was discovered by Lord Rayleigh and Sir W Ramsay in England It melts at 83 95 K, and boils at 87 45 K Many people don't realize that argon makes up a full 1% of our atmosphere, while carbon dioxide is only a fraction of a percent of our atmosphere Argon is primarily used to fill the empty space in incandescent light bulbs, and is used to create a greenish color in "neon" lights Argon is 2 5 times as soluble in water as nitrogen, and has about the same solubility as oxygen Argon is very inert, but it does form a hydrate, and ion molecules such as (ArKr)+, (ArXe)+, and (NeAr)+ These, however, do not have true chemical bonds Natural argon has three stable and five radioactive isotopes At STP (20 degrees C, 1 atm), Ar has a density of 1 784 g/L
Weight of one liter at 0° C
It has a characteristic spectrum
A colorless, odorless element Uses include shield in arc welding, furnace brazing, electric and specialized light bulbs and for use in geiger-counting tubes, and lasers Hazard: May cause dizziness and drowsiness and rapid suffocation In liquid form, is extremely cold and may cause frostbite
1° C
and to a solid melting at -189
Argon is condensible to a colorless liquid boiling at -186
A noble gas, used in light bulbs, gas discharge lamps, lasers, and Geiger Counters
wt
Noble gas, symbol Ar, of atomic mass 40, that composes 0 93 by volume of dry air Argon is constantly produced in the earth's crust from the radioactive decay of 40K and is subsequently released into the atmosphere It is the most abundant of the inert gases in the atmosphere, and the third most abundant of all atmospheric constituents Argon was discovered by Rayleigh and Ramsay in 1894
7828 g
Argon is an inert gas which exists in very small amounts in the atmosphere. It is used in electric lights. a colourless gas that is found in very small quantities in the air and is sometimes used in electric light bulbs. It is a chemical element : symbol Ar (argos ; because it does not react chemically). Chemical element, chemical symbol Ar, atomic number
