Answer:
A) An atom bonds to have eight valence electrons to become stable.
Explanation:
The third shell would be empty so that the eight electrons in the second level would be outermost after the atom loses one electron.
The octet rule state explains that atoms bond an atom bonds to have eight valence electrons to become stable.
The octet rule is the rule that explains that an atom should have filled with eight electrons in its valence shell for the most stable state.
For example, an Oxygen atom that has six electrons in the outermost shell needs two more electrons in its valence shell to form a stable atom.
For example, if a sodium atom reacts with a chlorine atom to form sodium chloride as a product, Sodium (Na) has 11 electrons and only a single electron in its outermost shell while the chlorine atom has 17 electrons,7 out of them are in its outermost valence shell, sodium atom transfer its only valence electron to the chlorine atom because of this single electron transfer outermost shell of both sodium and the chlorine atom is completed with exactly eight electrons depicting the octet rule.
Hence, atom bonds to have eight valence electrons to become stable is the statement given by the octet rule.
