Dear trishlaparihar20th@gmail.com

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

The second query is not clear.

Solution for your first query,

Noble gases such as Ne, Ar, Kr, Xe, Rn are placed in separate group in the periodic table because:

1. They have completely filled octet hence have least tendency to react with other elements. They are extremely non-reactive.

2. They can occur in nature by themselves and don't need another element to stabilize them.
