Explain why Group 1 elements tend to form 1+ ions and Group 7 elements tend to form 1 – ions.

Step-by-Step Solution:
Step 1 of 3

Solution 27Q

1st group elements have the general electronic configuration of ns1.Thus they have a tendency to lose electron to attain the nearest noble gas configuration .Loss of an electron results in formation of +1 ion

17 group elements have the general electronic configuration of ns2np5.Hence they can easily attain the stable noble gas configuration(ns2np6) by addition of an electron .Addition of an electron results in formation of -1ion
