Answer:
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.
Explanation:
Answer:
Sodium commonly forms a
+
I
ion.
Explanation:
And thus the chemical formula for sodium sulfide is
Na2S , i.e. two sodium ions are required to form a neutral salt with
S2-
