Final answer:
The names of the given ionic compounds are magnesium chloride, potassium nitride, lithium sulfide, cesium fluoride, magnesium oxide, and strontium fluoride. Each compound is named by combining the cation's name with the anion's name, changing the anion's ending to '-ide'.
Step-by-step explanation:
Naming ionic compounds involves combining the name of the cation (the positive ion) with the name of the anion (the negative ion). Here are the names for the listed compounds:
- MgCl₂ is magnesium chloride.
- K₃N is potassium nitride.
- Li₂S is lithium sulfide.
- CsF is cesium fluoride.
- MgO is magnesium oxide.
- SrF₂ is strontium fluoride.
In each case, the metallic element name is written first, followed by the non-metal element with its ending changed to '-ide'. Also, remember that we do not use numerical prefixes in the names of ionic compounds; the ratios of ions are instead determined by the charges necessary to balance the overall charge of the compound.
