Question

18th group is called noble gasses . why?

Answer 1

ya dude.. group 18 is called Nobel gas because they are totally unreactive and their octet are also complete so they are called* nobelgas*

Answer 2

Heya !!!


Here's your answer !!

All the orbitals in the valence shell of the 18 th group elements are completely filled by electrons and it's very difficult to alter this stable arrangement by the addition or removal of electrons...

They exhibit very low chemical reactivity.

Thus they are called noble gases..


Hope this helps you :)
