1. why do non metals are electronegative?
  2. why do noble gases don't react?

Expert Answer:


Non-metals have 5-7 electrons in their valence shell.

So they have a strong tendency to gain electrons to form the stable octet configuration.

So they accept electrons readily to form electronegative ions.

This is the reason why non-metals are electronegative in nature.


All noble gases are already in a state of maximum stability and so do not enter into a chemical combination under normal conditions.

Their stability is so prominent that they do not even form diatomic molecules and exist as monoatomic gaseous atoms.
