When are atoms most stable?
A) when they have the fewest possible valence electrons
B) when they have the maximum number of unpaired electrons
C) when all of the electron orbitals in the valence shell are filled
D) when all electrons are paired

Question

Quizplus · Accepted Answer

Atoms are most stable when all electron orbitals in the valence shell are filled. This is known as the octet rule, which states that atoms tend to gain, lose, or share electrons to have eight electrons in their valence shell, making them more stable. This stability is due to a full valence shell and a lower energy state. Therefore, the correct option is C when all of the electron orbitals in the valence shell are filled.
