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. ... These elements can “expand their octet” and have more than eight valence electrons around the central atom.

Answer 2

Explanation:

the tendancy of atoms to have eight electrons in the valence shell is known as the octet rule or the rule of eight
