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)

The correct statement about lithium sulfide is:

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

Here's a brief clarification of the other statements:

1. **A molecular model of lithium sulfide would have two spheres.** - This statement is misleading; a proper molecular model would not necessarily just consist of two spheres since it also includes sulfur.

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

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