When writing formula, the positive atom or ion comes first followed by the name of the negative ion. The chemical name for common table salt is sodium chloride. The periodic table shows that the symbol for sodium is Na and the symbol for chlorine is Cl. The chemical formula for sodium chloride is NaCl.

Answer:
When naming ionic compounds, we follow the general rules:
1. Identify and name the cation; this is a metal element or polyatomic cation.
2. Identify and name the anion; this is a nonmetal element. Change the suffix to '-ide,' or use the polyatomic anion name.
