The octet rule states atoms tend to:
AAchieve 8 electrons in their outermost shell (valence)
BLose all electrons
CHave only 1 electron
DBecome radioactive
Answer & Solution
Correct answer: A. Achieve 8 electrons in their outermost shell (valence)
Most atoms become chemically stable when their valence shell has 8 electrons (like noble gases). They achieve this by losing, gaining, or sharing electrons. Hydrogen/helium follow a 2-electron 'duet' rule.
