types:
atmosfera
the envelope of gases surrounding any celestial body
cloro
a common nonmetallic element belonging to the halogens; best known as a heavy yellow irritating toxic gas; used to purify water and as a bleaching agent and disinfectant; occurs naturally only as a salt (as in sea water)
fluoro
a nonmetallic univalent element belonging to the halogens; usually a yellow irritating toxic flammable gas; a powerful oxidizing agent; recovered from fluorite or cryolite or fluorapatite
idrogeno,
idrossido
a nonmetallic univalent element that is normally a colorless and odorless highly flammable diatomic gas; the simplest and lightest and most abundant element in the universe
azoto
a common nonmetallic element that is normally a colorless odorless tasteless inert diatomic gas; constitutes 78 percent of the atmosphere by volume; a constituent of all living tissues
idrossido,
liceale,
ossigeno,
tessitura
a nonmetallic bivalent element that is normally a colorless odorless tasteless nonflammable diatomic gas; constitutes 21 percent of the atmosphere by volume; the most abundant element in the earth's crust
butano
occurs in natural gas; used in the manufacture of rubber and fuels
propano
colorless gas found in natural gas and petroleum; used as a fuel
esalazione
gases ejected from an engine as waste products
aria
a mixture of gases (especially oxygen) required for breathing; the stuff that the wind consists of
etilene
a flammable colorless gaseous alkene; obtained from petroleum and natural gas and used in manufacturing many other chemicals; sometimes used as an anesthetic
formaldeide
a colorless poisonous gas; made by the oxidation of methanol
metano
a colorless odorless gas used as a fuel
ozono
a colorless gas (O3) soluble in alkalis and cold water; a strong oxidizing agent; can be produced by electric discharge in oxygen or by the action of ultraviolet radiation on oxygen in the stratosphere (where it acts as a screen for ultraviolet radiation)
cielo
the atmosphere and outer space as viewed from the earth
argo
a colorless and odorless inert gas; one of the six inert gases; comprises approximately 1% of the earth's atmosphere
elio
a very light colorless element that is one of the six inert gasses; the most difficult gas to liquefy; occurs in economically extractable amounts in certain natural gases (as those found in Texas and Kansas)
cripto
a colorless element that is one of the six inert gasses; occurs in trace amounts in air
neon
a colorless odorless gaseous element that give a red glow in a vacuum tube; one of the six inert gasses; occurs in the air in small amounts
radon
a radioactive gaseous element formed by the disintegration of radium; the heaviest of the inert gasses; occurs naturally (especially in areas over granite) and is considered a hazard to health
xeno
a colorless odorless inert gaseous element occurring in the earth's atmosphere in trace amounts
