Radon is a colorless, odorless, and tasteless [15] gas and therefore is not detectable by human senses alone. At standard temperature and pressure, it forms a monatomic gas with a density of 9.73 kg/m 3, about 8 times the density of the Earth's atmosphere at sea level, 1.217 kg/m 3. [16]
At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by-product of petroleum refining. Its chief use is as feedstock for ethylene production. The ethyl group is formally, although rarely practically, derived from ethane.
The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. [34] They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds .
Carbon monoxide is an odorless and colorless gas that can build up in enclosed or partially enclosed spaces, poisoning people and animals who breathe in too much, according to the CDC. The gas can ...
Argon is colorless, odorless, nonflammable and nontoxic as a solid, liquid or gas. [11] Argon is chemically inert under most conditions and forms no confirmed stable compounds at room temperature. Although argon is a noble gas, it can form some compounds under various extreme conditions.
It is a colorless, odorless noble gas that occurs in trace amounts in the atmosphere and is often used with other rare gases in fluorescent lamps. Krypton is chemically inert . Krypton, like the other noble gases, is used in lighting and photography .
Isobutane is a colorless, odorless gas. It is the simplest alkane with a tertiary carbon atom. Isobutane is used as a precursor molecule in the petrochemical industry , for example in the synthesis of isooctane .
Methane is an odorless, colourless and transparent gas at standard temperature and pressure. [15] It does absorb visible light, especially at the red end of the spectrum, due to overtone bands , but the effect is only noticeable if the light path is very long.
