Explanation:
All in this group are characterized by the presence of
7e^- 7e−in an outer shell, and hence have the ability to gain an e^- e − to form negative ions w/ a completed octet of valence e^- e- All these elements share traits of being very reactive and in particular form substitution compounds w/ numerous organic compounds.
Although these elements also have other valences all have a -1
-1valence in common.
