Final answer:
The correct chemical names for the ionic compounds are: MgCl2 is Magnesium Chloride, BeF2 is Beryllium Fluoride, and Al2O3 is Aluminum Oxide. It's essential to use the correct chemical symbols and ion valencies when naming ionic compounds.
Step-by-step explanation:
Chemical Names of Ionic Compounds
The chemical names of the given ionic compounds can be determined by combining the names of the cation (positive ion) and the anion (negative ion). Here are the correct names for the compounds:
- MgCl2 is Magnesium Chloride.
- BeF2 is Beryllium Fluoride.
- Al2O3 is Aluminum Oxide.
It's important to note that there were mistakes in the initial solutions given in the reference information, which have now been corrected. Ensure to always consider the correct chemical symbols and valencies of the ions when naming the ionic compounds.
