In a molecule of lithium sulfide, there are two atoms of lithium and one atom of sulfur. Which statement about lithium sulfide is correct?(1 point) Responses The atoms in lithium sulfide are held together by bonds. The atoms in lithium sulfide are held together by bonds. The chemical formula for lithium sulfide is LiS2. The chemical formula for lithium sulfide is LiS 2 . Both lithium and sulfur form positive ions. Both lithium and sulfur form positive ions. A molecular model of lithium sulfide would have two spheres.

The correct statement about lithium sulfide is:

**The atoms in lithium sulfide are held together by bonds.**

Here’s a breakdown of why the other statements are incorrect:

1. **The chemical formula for lithium sulfide is LiS2.** - Incorrect. The correct formula is Li2S, as there are two lithium atoms for every one sulfur atom.

2. **Both lithium and sulfur form positive ions.** - Incorrect. Lithium (Li) does form positive ions (Li⁺), but sulfur (S) typically forms negative ions (S²⁻), not positive ions.

3. **A molecular model of lithium sulfide would have two spheres.** - Incorrect. While there may be two lithium atoms, the formula is Li2S, which means the model would actually include three spheres (two for lithium and one for sulfur).

Thus, the only accurate statement is that the atoms in lithium sulfide are held together by bonds.
