Naming and Charges of Ionic Compounds

The video tutorial explains how to name the compound FeCl3 as iron(III) chloride. It begins by identifying the elements iron and chlorine on the periodic table and explains that the compound is ionic. The tutorial then discusses the importance of specifying the charge of transition metals, like iron, using Roman numerals. It calculates the charge of iron based on the known charge of chlorine and the need for charge balance, leading to the final name iron(III) chloride.

What is the first step in naming FeCl3 according to the periodic table?

• Determine the charge of iron

• Write the formula

• Replace 'ine' with 'ide'

• Identify the metal and non-metal

What suffix is used when naming the non-metal in an ionic compound?

• ate

• ide

• ous

• ine

Why is it important to specify the charge of iron in FeCl3?

• Iron can have multiple charges

• Iron is a non-metal

• Chlorine has a variable charge

• It affects the color of the compound

How many chlorine atoms are present in FeCl3?

• Three

• Two

• One

• Four

What is the charge of each chlorine atom in FeCl3?
