Which Is The Correct Order For The Names And Formulas Of Binary Ionic Compounds

The correct order for the names and formulas of binary ionic compounds follows the convention of writing the cation (positively charged ion) first, followed by the anion (negatively charged ion). The formula is determined by balancing the charges of the cation and anion to create a neutral compound.

For example, sodium chloride is a binary ionic compound that consists of the cation Na+ and the anion Cl-. Therefore, the correct order for the name and formula of this compound is:

Name: Sodium chloride

Formula: NaCl

Another example is magnesium oxide, which consists of the cation Mg2+ and the anion O2-. Therefore, the correct order for the name and formula of this compound is:

Name: Magnesium oxide

Formula: MgO
