(a) Name the compounds.

1. BaI₂

2. MgO

(b) Write the formula of the compounds

1. Sodium sulfide

2. Potassium fluoride

Strategy

For part a, write the name of the cation followed by the name of the anion as it appears in Table 2.3; then reverse that strategy for part b, being careful to balance the charges to zero with appropriate subscripts.
