Ionic Compounds and Their Properties

This video tutorial explains how to name type 2 ionic compounds, which consist of metals from groups 3 to 12 and 14, and nonmetals. These metals can have multiple charges, making them multivalent. The video details the steps for naming these compounds, emphasizing the use of Roman numerals to indicate the metal's charge. Examples include naming FeCl3 as iron(III) chloride and CoF2 as cobalt(II) fluoride. The video concludes with practice problems and encourages viewers to explore more chemistry content.

What is a key characteristic of Type 2 ionic compounds?

• They contain only nonmetals.

• They have metals with fixed charges.
