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. A molecular model of lithium sulfide would have two spheres. A molecular model of lithium sulfide would have two spheres. Both lithium and sulfur form positive ions. Both lithium and sulfur form positive ions. The chemical formula for lithium sulfide is LiS2

The correct statement about lithium sulfide is: **The atoms in lithium sulfide are held together by bonds.**

Here's a brief explanation of why the other statements are incorrect:

- **A molecular model of lithium sulfide would have two spheres.**: This is misleading because a lithium sulfide model would actually include two lithium atoms and one sulfur atom, resulting in three spheres total.

- **Both lithium and sulfur form positive ions.**: This is incorrect; lithium forms a positive ion (Li⁺) while sulfur typically forms a negative ion (S²⁻).

- **The chemical formula for lithium sulfide is LiS2.**: This is also incorrect; the correct chemical formula for lithium sulfide is Li₂S, indicating two lithium atoms for every one sulfur atom.
