They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.

Noble gases have their outer valence orbit completely fill. Thus no scope of their reactivity with any element in absence of free valence electron.

Due to its completely filled outermost shell.

All subjects (upto 8th),Maths & Science (9-10th)

All the atoms are found to react with any other atom just to fill its outermost shell. In case of noble gases, their outermost shells are already fulfilled. Therefore in general noble gases are found to be very stable.

Nobel gases are inert so they do not react with any other so these are stable.

i believe in authantic teaching. basic concepts of a child makes the subject easy and intresting. i am working on this feild for last ten years and got very good results children who dare with maths get intrest in it and perform excelent in their exams maths become fun for them

Atoms react with other atom to complete its outer most orbit to get stability. But inert gasses have already their outer most orbit completely filled so they are stable.

Every atom reacts with another to complete its octate or duplet (as per requirement) in the outer most shells but Nobel gases have already completely filled outermost shells so they do not react.

All Nobel gases have a duplet or octet structure in their outer most orbit. Hence do not react with other elements under normal circumstances. On account of this they are also called as 'Inert Gases'

They are the Group 18 atom and their outer most shell are completely filled. So, they didn't react to any other atom of different group.
