The video tutorial explains how to name the ionic compound NaI, which consists of a metal (sodium) and a nonmetal (iodine). It describes the process of naming the metal as it appears on the periodic table and changing the nonmetal's ending to 'IDE' to form 'sodium iodide'. The tutorial also covers balancing the charges of sodium and iodide ions to ensure the compound is neutral. Dr. B concludes the tutorial by summarizing the naming process.

What type of compound is formed when a metal and a nonmetal combine?

• Organic compound

• Metallic compound

• Ionic compound

• Covalent compound

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

• Add a prefix to the metal name

• Use the Latin name of the metal

• Name the nonmetal first

• Name the metal as it appears on the periodic table

How do you modify the name of the nonmetal in a binary ionic compound?

• Add 'ate' to the end

• Add 'ide' to the end

• Add 'ium' to the end

• Add 'ite' to the end

What is the name of the compound NaI?

• Sodium iodate

• Sodium iodide

• Sodium iodite

• Sodium iodine

What is the charge of a sodium ion?

• 2+

• 1+

• 2-

• 1-

How many iodine atoms are needed to balance one sodium atom in NaI?

• No iodine atoms

• Three iodine atoms

• Two iodine atoms

• One iodine atom
