Select the item which does not belong to the following group -1. Zinc2. Neon3. Helium4. Xenon

Answer» Correct Answer - Option 1 : Zinc

The logic followed here is:

  • Neon, Helium, and Xenon are noble gases or inert gases whereas Zinc is a metal. 

Hence, Zinc does not belong to the group.

  • Neon (Ne), Helium(He), and Xenon (Xe) belong to group 18.
  • Zinc (Zn)  is brittle and silvery greyish in colour. It belongs to group 12 of the periodic table.
