Question

Define octet rule write its significance and limitation

Answer 1

Explanation:

significance of octet rule

the octet rule successfully explains the formation of chemical bonds depending upon the nature of the element .It is used to

determine stability in atoms .some limitations of the octet rule are :it can't be

applied to the non metals after silicon in the periodic table .

Answer 2

Answer:

Octet rule

The rule states that every atom combine or react in order to have an octect ie, to have 8 electrons in the valence shell

significance :

This law is significant in describing the less reactive nature of noble

Limitations:

Incomplete octect: some compounds only contain less than 8 electrons in their valence shell and therefore violate the law

eg: Becl2

Expanded octect: some compound combine more than 8 electrons in their valence shell and thus stood against this rule , eg PC15

compounds with odd number of electrons in the valence shell: some compound contain odd number of electrons in the valence shell and violate this law

eg: NO
