Which of the following elements is most likely to form a molecule or ion that exceeds the octet rule?Group of answer choicesNFSCB

The octet rule states that atoms are most stable when their outermost shell is full, typically with eight electrons. However, there are exceptions to this rule.

Atoms that are in the third period (row) of the periodic table or beyond can hold more than eight electrons. This is because they have d orbitals available in their valence shell that can accommodate extra electrons.

Looking at the given options: N (Nitrogen), F (Fluorine), S (Sulfur), C (Carbon), and B (Boron), only Sulfur (S) is in the third period of the periodic table. Therefore, Sulfur (S) is the element most likely to form a molecule or ion that exceeds the octet rule.
