Naming and Properties of Calcium Iodide

The video tutorial explains how to name the compound CI2 by identifying its components as a metal and a non-metal, treating it as an ionic compound. It details the process of naming the metal calcium and the non-metal iodine, replacing the ending with 'ide' to form calcium iodide. The tutorial also covers writing the formula for calcium iodide by balancing the ionic charges of calcium (2+) and iodide (1-), requiring two iodide ions to balance one calcium ion.

What is the first step in naming the compound CI2?

• Write the chemical formula

• Balance the ionic charges

• Identify the non-metal component

• Identify the metal component

How do you modify the name of the non-metal in CI2?

• Add 'ium' to the end

• Replace the ending with 'ide'

• Keep the name unchanged

• Add 'ate' to the end
