1.	What’s the group valance of atoms in the halogen family?(a) 2(b) 1(c) 9(d) 7The question was asked in an interview for job.This interesting question is from Kossel-Lewis Approach to Chemical Bonding in division Chemical Bonding and Molecular Structure of Chemistry – Class 11
Answer» The CORRECT option is (b) 1 Explanation: The group valance can be calculated from Lewis symbols either by subtracting it from eight (more than 4) or having it equal (less than 4). The halogen family has 7 ELECTRONS in their outer orbit. So 8 – 7 = 1. Therefore the valency of the halogen family is 1.
