Use Lewis theory to determine the chemical formula for the compound formed between Li and S. A) LiS B) LiS₂ C) Li₂S D) Li₂S₃ E) Li₃S₂

Question

Quizplus · Accepted Answer

Lithium (Li) has one valence electron and tends to lose it to achieve a stable electron configuration, forming Li⁺. Sulfur (S) has six valence electrons and tends to gain two electrons to achieve a stable configuration, forming S²⁻. Therefore, two Li⁺ ions are needed to balance the charge of one S²⁻ ion, resulting in the formula Li₂S.
