What is the octet rule, and which family of elements already obeys it?
Original Khojo Papers practice question — not from a past board paper.
Answer
The octet rule states that atoms combine so as to attain eight electrons in their outermost shell, the arrangement of a noble gas. The noble gases already have it, which is why they are chemically inert.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Helium is the exception, being stable with two electrons.
