Osmium This is totally incorrect. Osmium has the tenth highest melting point of all elements and therefore cannot be a gas at room temperature. Radon is heavier and also a gas. The atomic weight of radon is 222 atomic mass units making it the heaviest gas known. It is also radioactive and can collect in basements/cellars of homes. From Wikipaedia :: According to the United States Environmental Protection Agency, radon is the second most frequent cause of lung cancer, after cigarette smoking, causing 21,000 lung cancer deaths per year in the United States......

Thanks for the feedback!
Helium is an element which is in the form of gas at room temperature. Why not other inert gasses too are good examples. Neon, Argon, xenon
you can tell whether the element is a liquid or gas by the melting/boiling points if it's greater than 20 degrees Celsius then it will be a solid, if the element's melting… point is less than 20 degrees Celsius the element will be a gas. There are only two elements that are liquid at room temperature and they are Mercury (Hg) and Bromine (Br).
Carbon Oxygen Argon Nitrogen (there are even more)
Steam. Notice that it condences (becomes a liquid) when it touches a window or something with a cold surface. However... it is still steam (gas) when it is in the air
It depends on the element! Hydrogen, oxygen, nitrogen, fluorine, chlorine and all of the noble gases are gases at room temperature and 1 atmosphere pressure.
Nitrogen is an element that is a gas at room temperature. Nitrogen is part of group V in some versions of the periodic table, although in modern textbooks in which the periodi…c table is usually shown in periods with the transition elements in separate groups, nitrogen is part of group 15.
yes. at least the last time i breathed it was........
Examples: nitrogen, oxygen, hydrogen, argon etc.
The elements hydrogen, helium, nitrogen, oxygen fluorine, neon, chlorine, argon, xenon, krypton, and radon are gasses at room temperature.
Chlorine is an element that is a gas at room temperature.
Liquid: mercury. Gas: neon.
