Characteristics and properties under standard conditions nitrogen is a colorless tasteless odorless gas it forms diatomic molecules which means that there are two nitrogen atoms per molecule in nitrogen gas n 2 in this configuration nitrogen is very inert meaning that it doesnt typically react with other compounds. Density g cm 3 density is the mass of a substance that would fill 1 cm 3 at room temperature relative atomic mass the mass of an atom relative to that of carbon 12 this is approximately the sum of the number of protons and neutrons in the nucleus where more than one isotope exists the value given is the abundance weighted average isotopes. Nitrogen dioxide appears as a reddish brown gas or yellowish brown liquid when cooled or compressed shipped as a liquefied gas under own vapor pressure vapors are heavier than air toxic by inhalation vapor and skin absorption. The above list is useful because of the following fact if a function fn is a sum of functions one of which grows faster than the others then the faster growing one determines the order of fn example if fn 10 logn 5 logn3 7 n 3 n2 6 n3 then fn on3 one caveat here the number of summands has to be constant and
