CBSE Class 11-science Answered
- why do non metals are electronegative?
- why do noble gases don't react?

Expert Answer
1.
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.
2.
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.
