Colourless is a property, or word to describe matter, however the "gas" would be something you're describing. However, if a reaction is omitting a colourless gas, it could be considered a physical property of the reaction.
Radon is a noble gas element and is classified as a nonmetal. It is colorless, odorless, and tasteless, making it difficult to detect without specific testing equipment.
Argon is a nonmetal. It is a noble gas that is colorless, odorless, and tasteless. Argon is typically inert and nonreactive with other elements.
Helium is a nonmetal. It is a colorless, odorless, and tasteless gas that does not possess the typical properties of a metal or metalloid.
Helium is a nonmetal, a gas.
Radon is an inert or noble gas, and that's as far from being a metal as an element can get. You'll find radon at the bottom of the Group 18 elements (naturally) on the periodic table. Use the link below for more information.
Xenon is a nonmetal. It is a colorless, odorless gas found in the Earth's atmosphere.
Helium is a nonmetal. Think about the helium balloon!
Helium is a nonmetal. Think about the helium balloon!
SO2 is sulphur dioxide, at standard atmosphere it is a toxic gas with a pungent smell
Radon is a noble gas element and is classified as a nonmetal. It is colorless, odorless, and tasteless, making it difficult to detect without specific testing equipment.
Helium is a nonmetal. It is a colorless, odorless, and tasteless gas that is found in small amounts in the Earth's atmosphere.
Neon is nonmetal since it's a colorless odorless gas .
Xenon is achemical element and a Non Metal
Argon is a nonmetal. It is a noble gas that is colorless, odorless, and tasteless. Argon is typically inert and nonreactive with other elements.
Nitrogen
No. Argon is a nonmetal, and furthermore, a gas.
Yes, Rn is radon a radioactive nonmetal. But the symbol Rn does not stand for "radioactive nonmetal." Rn Radon has no stable isotopes, so yes it is always a radioactive nonmetal.
