An element X of group 15 exists as diatomic molecule and combines with hydrogen at 773 K in presence of the catalyst to form a compound, ammonia which has a characteristic pungent smell
(a) Identify the element X. How many valence electrons does it have ?
(b) Draw the electron dot structure of the diatomic molecule of X. What type of bond is formed in it ?
(c) Draw the electron dot structure for ammonia and what type of bond is formed in it ?

Explanation

(a) The available information suggests that the demcnt X is nitrogen (N) and exists Ill diaromic form as `N_(2)` Electronic configuration of N(Z = 7) , 2, 5. It has five valence electrons.
