    Which statement correctly describes the formation of a sulfide ion (S2−\text{S}^{2-}) from a neutral sulfur atom (Z=16Z = 16)?

    • A) The sulfur atom loses two protons from its nucleus, giving it a net 2−2- charge.
    • B) The sulfur atom gains two valence electrons to achieve the stable electron configuration of argon.
    • C) The sulfur atom loses six valence electrons to empty its outermost shell and form an octet.
    • D) The sulfur atom gains two protons and two electrons simultaneously to maintain nuclear stability.
