Question

What is octet rule.

Answer 1

Octet rule: The octet rule states that each atom tends to have eight electrons in its valence shell through forming bonds with other atoms.

Example: Carbon dioxide

• Carbon contains four electrons and oxygen contains six electrons in its valence shell.
• So, a carbon atom combines with two oxygen atoms by sharing two electrons with each oxygen atom.
• In this way the octet of both carbon and oxygen is completed.
