Answer :

(i) The largest non-metal constituent of air is nitrogen (N) and it is present as N2 gas .It reacts with hydrogen in presence of Fe catalyst to give Ammonia (NH3). Ammonia reacts with conc. H2SO4 to give ammonium sulphate (NH4)2SO4.

Thus A= Nitrogen (N)


B=Ammonia (NH3)


C= Ammonium sulphate (NH4)2SO4


(ii) Element A is Nitrogen. It lies in the 2nd period and 15th group of the modern periodic table.


(iii) Carbon comes before nitrogen and oxygen comes after nitrogen in the 2nd period.


(iv) The atomic number of nitrogen is 7. So, its electronic configuration is 2,5.
