Nitrogen can be a pure substance in gaseous, liquid or solid form. It is a iquid or a gas under normally attained pressures and temperatures. It can solidify at -219 C.It can be present in nitrogen oxides, nitrogen acids, the salts of nitrogen acids, ammonia, protein and a wide range of organic compounds.

Nitrogen gas in the air is converted into usable forms by soil bacteria through a process called nitrogen fixation. Plants then take up these forms of nitrogen from the soil. When organisms consume plants, they obtain nitrogen from the plants, and the nitrogen cycles through the food chain as organisms are consumed by other organisms.
Hydrogen: 1 Oxygen: 2 Nitrogen:3 Carbon: 4
Nitrogen is not a compound
Atmospheric nitrogen is converted to terrestrial forms by nitrogen-fixing bacteria. These bacteria convert atmospheric nitrogen into ammonium through a process called nitrogen fixation. Plants then take up this ammonium and use it to produce proteins and other nitrogen-containing molecules, which are then consumed by animals. This allows the nitrogen to be cycled through the ecosystem.
Nitrogen forms gaseous oxides. NO,NO2,N2O,N2O3 are few examples.
A nitrogen atom can form three bonds at most as it shows valency of three.
Nitrogen can form three covalent bonds when it has no negative charge.
it forms a triple bond
3 bonds are commonly formed by nitrogen and 2 are commonly formed by oxygen.
Forms of nitrogen found in the hydrosphere include nitrate (NO3-), nitrite (NO2-), and ammonium (NH4+). These forms of nitrogen can result from natural processes like nitrogen fixation by bacteria, as well as human activities such as agricultural runoff.
Nitrogen is available to plants in the form of nitrates (NO3-) or ammonium (NH4+). Plants typically take up these forms of nitrogen through their roots for growth and development.
