Relative atomic mass the mass of an atom relative to that of.

Nitrogen state at room temperature.

It is represented by the symbol n and has an atomic number of 7 in the periodic table. Below 63 k it freezes into solid nitrogen. A nitrogen atom has seven electrons. Molecular nitrogen is bound by a trivalent bond which is one of the strongest in nature.

320 f boiling point at sea level it is produced industrially by fractional distillation of liquid air it is a colorless low viscosity liquid that is widely used as a coolant. However at low temperature and or high pressures the gas becomes a liquid or a solid. The curve between the critical point and the triple point shows the nitrogen boiling point with changes in pressure. Density g cm 3 density is the mass of a substance that would fill 1 cm 3 at room temperature.

The temperature at which the liquid gas phase change occurs. At normal atmospheric pressure nitrogen is a liquid between 63 k and 77 2 k 346 f and 320 44 f. It has one of the highest electronegativities among the elements 3 04 on the pauling scale exceeded only by chlorine 3 16 oxygen 3 44. The next most common gas is oxygen at 21.

Sublimation the transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Nitrogen with chemical formula n2 is a non metallic element found in the gaseous state at room temperature. Nitrogen was discovered by the scottish physician daniel rutherford in 1772. The nitrogen phase diagram shows the phase behavior with changes in temperature and pressure.

The earth s atmosphere is made up of 78 nitrogen. It is the fifth most abundant element in the universe and makes up about 78 of the earth s atmosphere which contains an estimated 4 000 trillion tons of the gas nitrogen is obtained from liquefied air through a process known as fractional distillation. In the ground state they are arranged in the electron configuration 1s 2 2s 2 2p 1 x 2p 1 y 2p 1 z it therefore has five valence electrons in the 2s and 2p orbitals three of which the p electrons are unpaired. Nitrogen density and specific weight online calculator figures and tables showing density and specific weight of nitrogen n 2 at temperatures ranging from 175 to 1325 c 280 to 2400 f at atmospheric and higher pressure imperial and si units.

Over this temperature range liquid nitrogen looks much like boiling water. Liquid nitrogen ln 2 is nitrogen in a liquid state at low temperature 195 79 c 77 k. Nitrogen has a low melting and boiling point and is a gas at room temperature. Because liquid nitrogen in a usual setting is boiling its usual temperature is 77 k.
