Question

directions: write the name for each of the following ionic compounds.
10.) mgo
(1 point)
○ magnesium oxide
○ magnesium (ii) oxide
○ magnesium oxygen
○ manganese oxide

Explanation:

Mg is magnesium, a group 2 metal that only forms a +2 ion, so no Roman numeral is needed. O is oxygen, which forms the oxide anion. The compound is named by stating the cation first, then the anion. "Magnesium (II) Oxide" is unnecessary because magnesium only has one common charge. "Magnesium Oxygen" uses the element name instead of the anion name, and "Manganese Oxide" uses the wrong metal (Mn is manganese, not Mg).

Answer:

Magnesium Oxide
