Use ideas about electronic structure to explain why the noble gases are unreactive.

the nobel gases are unreactive bcz it alredy has stable electronic configuration due to which it neither donate nor receive electrons during the chemical reaction so, it is are unreactive ...

Noble gases are nonreactive because their duplet and octet is complete. They no more need any electron to complete their duplet or octet. Elements are usually reactive because they tend to lose and gain electrons and Since noble gases have no tendency to gain or lose electrons, They are inert, noble and nonreactive.
