An ionic formula, like NaCl, is an empirical formula. This formula merely indicates that sodium chloride is made of an equal number of sodium and chloride ions. Sodium sulfide, another ionic compound, has the formula Na2S

Sodium Sulfate is an ionic compound formed by two ions, Sodium Na+ and Sulfate SO−24 . In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it will take two +1 sodium ions to balance the one -2 sulfate ion. This will make the formula for Sodium Sulfate Na2SO4 .

Answer 2

Explanation:

compounds, except that we use the name of the polyatomic ion whenever it occurs. For example, NaNO2 is named according to its cation, Na+ (sodium), and its polyatomic anion, N03 (nitrite). Its full name is sodium nitrite.
