A non-metal A which is the largest constituent of air combines with hydrogen on heating in the presence of Fe (as catalyst) and forms a gas B. When this gas B is treated with H²SO4, compound C is formed which is broadly used as chemical fertiliser. 
(¡) identify A, b and C. 
(¡¡)locate the position of A in the mordern periodic table. 
(¡¡¡)which elements are present before and after the element A ?
(¡v) write the electronic configuration of element A.

Expert Answer:

Non-metal A is Nitrogen which is the largest constituent of air combines with hydrogen on heating in the presence of Fe (as catalyst) and forms a gas B i.e., Ammonia NH3
N subscript 2 space space plus space space 3 H subscript 2 space rightwards arrow over leftwards arrow from 450 minus 500 to the power of 0 C to F e divided by M o of space space space 2 N H subscript 3 space space space plus space h e a t
 
When this ammonia gas is treated with H2SO4, compound C i.e. ammonium sulphate is formed which is broadly used as chemical fertiliser. 
2 N H subscript 3 space end subscript space plus space space H subscript 2 S O subscript 4 space rightwards arrow for space space of space space left parenthesis N H subscript 4 right parenthesis subscript 2 S O subscript 4
 
i) Compound A is Nitrogen Compound B is Ammonia and compound C is Ammonium nitrate.
ii) Position of Nitrogen in periodic table = Group is 15, VA and period is 2
iii) Carbon is present before the Nitrogen and Oxygen is present after the oxygen.
iv) electronic configuration of nitrogen : 1s2 2s2 2p3
