Define octet rule. Write its significance and limitations.
Answers
Answer:
octet rule tells that a atom shoul have valency electon as 8 to make it stable
it is good to stable the atom
its limitations is that it may vary from weight
Explanation:
The octet rule dictates that atoms are most stable when their valence shells are filled with eight electrons.
SIGNIFICANCE :
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. The octet rule helps to figure out how atoms will bond with one another.
LIMITATIONS :
It cannot be applied to the nonmetals after silicon in the Periodic Table. These elements can “expand their octet” and have more than eight valence electrons around the central atom. Molecules with an odd number of electrons such as NO and NO₂ cannot satisfy the octet rule.
