why nitrogen is important in human which molecules contain nitrogen

Nitrogen - Nitrogen forms nearly 78% of the volume of air. Earlier, the useful significance of nitrogen was not known and it was considered to be inactive. At that time, nitrogen was considered important only because it was known to moderate the pro..

Introduction - Functional groups containing nitrogen are present in a variety of naturally occurring and man made organic compounds. These functional groups impart physico- chemical characteristics to these molecules. These groups are responsible for their unique chemi..

Nitrogen - In 1772 Daniel Rutherford discovered Nitrogen. Nitrogen is the first member of group 15 of the periodic table. Nitrogen exists as a diatomic molecule (N 2 ) with a triple bond between the nitrogen atoms (NN)...

In 1772 Daniel Rutherford discovered Nitrogen. Nitrogen is the first member of group 15 of the periodic table. Nitrogen exists as a diatomic molecule (N 2 ) with a triple bond between the nitrogen atoms (NN). So nitrog..

N 2 molecule has 14 electrons. fig 1.19 - Molecular orbital energy level diagram for N 2 moleculeThe molecular orbital electronic configuration of the molecule is: N 2 : KK( s 2s) 2h..

2 ) molecule Nitrogen has three half-filled orbitals. In the formation of nitrogen molecule, each of the three half-filled '2p' orbitals of one nitrogen atom overlaps with the corresponding orbitals of second nitrogen..

Nitrogen is obtained from the soil in the form of nitrates (NO 2 - ), nitrites (NO 3 - ) and ammonium (NH 4 + ) sal..

Nitrogen Metabolism in Plants - Nitrogen is one of the important elements found in living organisms. Supply of nitrogen from the atmosphere is maintained. Nitrogen is an essential constituent of amino acids and hence the proteins cannot be absorbed ..
