Answer:

Q3.27

1)nitrogen

2)An element having two valence electrons will lose two electrons easily to attain the stable noble gas configuration. The general electronic configuration of such an element will be ns2. This is the electronic configuration of group 2 elements.

3)An element is likely to gain two electrons if it needs only two electrons to attain the stable noble gas configuration. Thus, the general electronic configuration of such an element should be ns2 np4. This is the electronic configuration of the oxygen family i.e O(2p4), S(3p4), Se(4p4), Te(5p4), Po(6p4), Uuh(7p4).
