Question

23. Explain :
(a) octet rule for formation of a chemical compund.
(b) duplet rule for formation of hydrogen.


​

Answer 1

Answer:

The octet rule is a chemical rule of thumb that reflects observation that elements tend to bond in such a way that each atom has eight electrons in its valence shell , giving it the same electronic configuration as a noble gas.

Duplet rule is found only for some smaller atoms like hydrogen etc which gain or lose electrons to obtain a stable duet like helium gas and other noble gas .
