Gases can be elements or compounds. The elements that are gases at room temperature are hydrogen, nitrogen, oxygen, fluorine, chlorine and all of the noble gases. Fluorine is also the most reactive nonmetal. An
Name five substances which are solids, five substances which are liquids and five substances which are gaseous at room temperature. View Solution How many elements are gases at room temperature ? View Solution কার্বন টেট্রাক্লোরাইড, ফস...
Most elements of the periodic table are solid at room temperature. Some of them are gases at room temperature. The gas elements are all noble gases plus nitrogen, oxygen, fluorine, chlorine and hydrogen. There are only two elements with the liquid state among all elements....
As the name suggests, compressed gases are essentially chemical elements that are stored under pressure, usually in a cylinder, canister or tube trailer. They don't become liquid when compressed at room temperatures, with common examples including oxygen, nitrogen, argon and helium. Want to know ...
Here are some steps the industry could take in the short term: Gas abatement systems could be installed to transform harmful gases into ones with less global warming potential. Heat transfer fluids could be replaced with ones that have less global warming potential. ...
Similarly, hydrogen and oxygen, which are both gaseous elements can combine to form water, which is a liquid compound, not a gas, at room temperature. The process by which such combinations and transformations of elements into compounds take place is called achemical reaction. ...
Integrated circuits like microchips are composed of semiconductor materials. At extremely low temperatures, metals conduct electricity better than any known substance at room temperature. This phenomenon is calledsuperconductivity. A substance that behaves in this way is called asuperconductor. ...

and bond with other atoms to restore balance. The noble gases are outliers because their atoms already have the maximum number of electrons, and therefore they don't exchange with other elements. At least, not on Earth they don't, but scientists are discovering that noble gases behave differen...
Element names ending with -onare noble gases, which are inert or nonreactive gases at room temperature. Most element names end with -ium. These elements are metals, which are usually hard, shiny, and conductive. What youcannottell from an element name or symbol is how many neutrons or elec...
