Ionic compounds are written with

• cation (+ ion) first then anion (- ion)
• anion (- ion) first then cation (+ ion)
• either way is fine
• polyatomic ions first

The first step in naming an ionic compound is always...

• Naming the anion (non-metal)

• Changing the ending to -ide

• Naming the cation (metal)

• Writing the cation charge

Name the following ionic compound: MgSO₄

• magnesium sulfoxide

• magnesium sulfide

• magnesium sulfate

• magnesium oxide
