Types of Gases

air
air

Dry air is primarily made up of nitrogen (78.09%) and oxygen (20.95%). The remaining 1% is made up of argon (0.93%), carbon dioxide (0.039% as of 2010) and other trace gases (0.003%). Water vapor (water in its gaseous state) is also present in the atmosphere in varying amounts, by up to 2%.

Argon (Ar)
Argon (Ar)

Argon is a chemical element with symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas.[6] Argon is the third-most abundant gas in the Earth's atmosphere, at 0.934% (9340 ppmv).

Carbon Dioxide
Carbon Dioxide

Carbon dioxide (chemical formula CO2) is a naturally occurring colorless gas with a density about 60% higher than that of air (1.225 g/L) that is odorless at normally encountered concentrations.

Carbon Monoxide (CO)
Carbon Monoxide (CO)

Carbon monoxide detector Where is CO found? CO is found in fumes produced any time you burn fuel in cars or trucks, small engines, stoves, lanterns, grills, fireplaces, gas ranges, or furnaces.

Chlorine (Cl)
Chlorine (Cl)

Dry chlorine gas won’t bleach, but in water it forms hypochlorite, responsible for the bleaching action, and also responsible for its disinfectant action. It was first used to disinfect tap water at the time of a typhoid outbreak in Maidstone in 1897. Since then the process has been generally adopted.

Fluorine (F)
Fluorine (F)

Fluorine is a chemical element with symbol F and atomic number 9. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.

Freon
Freon

Freon (/ˈfriː.ɒn/ FREE-on) is a registered trademark of The Chemours Company, which uses it for a number of halocarbon products. They are stable, nonflammable, moderately toxic gases or liquids which have typically been used as refrigerants and as aerosol propellants.

Helium
Helium

Helium is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table.

Helium (He)
Helium (He)

Helium (from Greek: ἥλιος, translit. Helios, lit. 'Sun') is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements.

Hydrocarbons (HC)
Hydrocarbons (HC)

Aromatic hydrocarbons, also known as arenes, are hydrocarbons that have at least one aromatic ring. Hydrocarbons can be gases (e.g. methane and propane), liquids (e.g. hexane and benzene), waxes or low melting solids (e.g. paraffin wax and naphthalene) or polymers (e.g. polyethylene, polypropylene and polystyrene).

Hydrogen
Hydrogen

Hydrogen is a chemical element with symbol H and atomic number 1. With a standard atomic weight of circa 7000100800000000000♠1.008, hydrogen is the lightest element on the periodic table.

Natural gas
Natural gas

Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.

Neon (Ne)
Neon (Ne)

Neon is a chemical element with symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air.

Nitrogen
Nitrogen

Nitrogen gas has become the inert gas of choice for inert gas asphyxiation, and is under consideration as a replacement for lethal injection in Oklahoma. Nitrogen gas, formed from the decomposition of sodium azide, is used for the inflation of airbags.

Nitrogen (N)
Nitrogen (N)

Given the great reactivity of atomic nitrogen, elemental nitrogen usually occurs as molecular N2, dinitrogen. This molecule is a colourless, odourless, and tasteless diamagnetic gas at standard conditions: it melts at −210 °C and boils at −196 °C.

Oxides of Nitrogen (NOx)
Oxides of Nitrogen (NOx)

NOx is produced from the reaction of nitrogen and oxygen gases in the air during combustion, especially at high temperatures. In areas of high motor vehicle traffic, such as in large cities, the amount of nitrogen oxides emitted into the atmosphere as air pollution can be significant.

Oxygen (O)
Oxygen (O)

Oxygen is an element. A compound is two or more elements chemically combined. A mixture is two or more elements physically combined (ie. just mixed together). Oxygen gas is made of molecules containing only oxygen.

Oxygen (O2)
Oxygen (O2)

"Oxygen gas" is not an element. It is a compound (more specifically, it is a molecule or collection of molecules). "Oxygen" by itself can refer to the element oxygen, the oxygen atom, or the oxygen molecule O2.

Water Vapor
Water Vapor

Water vapor, water vapour or aqueous vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Unlike other forms of water, water vapor is invisible.
