How can I write the formula for sodium sulfide? | …

2014-6-12 · The formula for sodium sulfide is Na_2S. Since this is an ionic compound, you must balance the charges so that overall charge of the compound is neutral. Sodium, an alkali metal, has a tendency to lose one electron. As a result sodium normally carries a positive one charge. Sulfur, a nonmetal, has a tendency to gain 2 electrons. This results in an ion with a negative 2 charge.
