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.
