Mastering Ionic Compound Nomenclature with Roman Numerals

This video tutorial explains how to name ionic compounds with transition metals using Roman numerals. It covers the concept of ionic compounds, focusing on transition metals whose valence electrons are unpredictable. The tutorial provides examples of balancing charges in compounds like copper(III) oxide, silver phosphide, vanadium nitride, and titanium arsenide, demonstrating how to achieve a neutral charge by adjusting the number of ions.

What does the presence of Roman numerals in the name of an ionic compound indicate?

• The compound contains a nonmetal.

• The compound contains a transition metal.

• The compound contains a metal from the first two columns of the periodic table.

• The compound contains a noble gas.
