प्रश्न
Give a reason why the non-metals – halogens and noble gases are placed in separate groups of the periodic table with special reference to their difference in properties.

उत्तर
- Non-metals with halogens are highly reactive. Salts are easily formed when they react with metals. On the other hand, noble gases are inert or inactive due to their stable electronic configuration.
- Halogens typically exist as diatomic molecules whereas noble gases are monoatomic.
