Aluminum Phosphide and Ionic Compounds

The video tutorial explains how to identify and name binary ionic compounds, focusing on aluminum phosphide. It begins by recognizing ionic compounds as those formed by metals and non-metals. The tutorial outlines the naming process: writing the metal's name as it appears on the periodic table and modifying the non-metal's name to end with 'ide'. It also covers writing the chemical formula by balancing ionic charges, using aluminum phosphide as an example.

What type of compound is formed when a metal bonds with a non-metal?

• Organic compound

• Metallic compound

• Ionic compound

• Covalent compound

What is the first step in naming a binary ionic compound?

• Balance the equation

• Write the name of the metal

• Write the name of the non-metal

• Determine the ionic charge

How is the name of the non-metal modified in a binary ionic compound?

• Keep it unchanged

• Replace the ending with 'ide'

• Add 'ate' to the end

• Add 'ite' to the end
