Answer 3

[AI-generated answer — Explain Bot]

The chemical formula for lithium ion (Li+) and sulfide ion (S2-) is Li2S. To determine the chemical formula, you need to consider the charges of each ion and balance them.

Lithium has a +1 charge, which means it loses one electron to become a Li+ ion. Sulfur, on the other hand, has a -2 charge, which means it gains two electrons to become an S2- ion.

To balance the charges, you need two lithium ions, each with a +1 charge, to balance the overall -2 charge of the sulfide ion. Therefore, the chemical formula is Li2S.
