Binary Ionic Compounds and Naming

This video tutorial covers the naming and formula writing of binary ionic compounds with fixed oxidation state cations. It explains the rules for naming such compounds, including naming the cation first and modifying the anion's name. The video provides examples of common cations and anions, and demonstrates how to name compounds like aluminum oxide and lithium nitride. It also includes practice questions to reinforce learning.
