Both lithium and sulfur form positive ions.
Both lithium and sulfur form positive ions.

A molecular model of lithium sulfide would have two spheres.

Answer 1

The correct statement about lithium sulfide is:

The atoms in lithium sulfide are held together by bonds.

The correct chemical formula for lithium sulfide is Li2S, not LiS2. Lithium forms positive ions (Li+) while sulfur forms a negative ion (S2-). Therefore, the statement "Both lithium and sulfur form positive ions" is incorrect. Also, a molecular model of lithium sulfide would involve more than just two spheres, as it consists of multiple lithium ions and one sulfide ion in a crystal lattice structure rather than a discrete molecule.

Thus, the only accurate statement given is about the atoms being held together by bonds.
