WebAnswer: D. Solution: Since the valence shell of the elements in group 17 has seven electrons, their general electrical configuration is ns 2 np 5, or ns2np2 x 〖 np 〗2 y 〖 np 〗1 z,, where n=2 to 6 . As a result, they have one less electron than the nearby inert gas configuration. So, option D is the correct answer. Q3. Webelectrons, six groups 13 to 18 are there in p-block elements. We shall study group 13 and 14 i.e. Boron and carbon group elements in this unit.
