The next most common gas is oxygen at 21.
Why does nitrogen exist as a gas at room temperature.

The temperature of liquid nitrogen can readily be reduced to its freezing point 63 k 210 c.
Elements that are gases at room temperature are all nonmetals such as he ar n 2 o 2 and so on.
Liquid nitrogen s efficiency as a coolant is limited by the fact that it boils immediately on contact with a warmer object enveloping the object in insulating nitrogen gas.
The total increase in volume is 645 3 times which means vaporizing nitrogen exerts immense pressure on its surroundings.
From left to right.
Most metals exist as solids at room temperature.
Does nitrogen pressure change with temperature practical application of gas laws.
Some substances exist as gases at room temperature oxygen and carbon dioxide while others like water and mercury metal exist as liquids.
We all learned about them in school and promptly forgot all about them.
Each of the 13 elements has their own unique physical and chemical properties.
346 f by placing it in a vacuum chamber pumped by a vacuum pump.
Mercury hg and bromine br are the only elements in the periodic table that are liquids at room temperature.
The earth s atmosphere is made up of 78 nitrogen.
Compounds that are gases at room temperature are all covalent compounds such as co 2 so 2 and nh 3 that contain two or more nonmetals.
Nitrogen has a low melting and boiling point and is a gas at room temperature.
The state a given substance exhibits is also a physical property.
Then the gas expands another 3 7 times as it warms to room temperature.
The reason why these elements form gases at room temperature is that the diatomic molecules that they both form have relatively little attraction for eachother and therefore they move.
Radon helium xenon neon krypton and argon are eight noble gases.
Nitrogen also known as n2 or n n belongs to the class of inorganic compounds known as other non metal nitrides these are inorganic compounds of nitrogen where nitrogen has a formal oxidation state of 3 and the heaviest atom bonded to it belongs to the class of other non metals.
They are nonreactive mono atomic elements with extremely low boiling points.
Nitrogen has been found in human skin tissue and has also been primarily detected in urine.
I really think that we need to dig our books out dust that information off and work to understand and apply it.
