Question

explain in brief how atoms of other elements other than noble gas,attain stable electronic configuration of the nearest noble gas

Answer 1

hello..! 

they attain near stable electronic configuration of nobel gas by completing their octet and duet.
I'm taking an example of NaCl
chlorine requires 1 electron to complete its octet and attain Argon's structure
then it takes 1 electron from sodium.
so they both became stable!!
