Ionic Compounds and Naming Conventions

The video tutorial explains how to name the compound CuO, known as copper(II) oxide, using the periodic table and simple naming rules. It covers the identification of copper as a metal and oxygen as a non-metal, forming an ionic compound. The tutorial details the naming process, including the removal of 'ygen' from oxygen to form 'oxide'. It emphasizes the importance of specifying the charge for transition metals like copper, which can have multiple charges. The video concludes by explaining how to denote the charge using Roman numerals, resulting in the name copper(II) oxide.

What is the first step in naming CuO as Copper(II) Oxide?

• Use the periodic table and basic rules.

• Calculate the molar mass.

• Identify the compound as covalent.

• Determine the molecular geometry.

Why is CuO considered an ionic compound?

• Because it contains only non-metals.

• Because it is formed by a metal and a non-metal.

• Because it has a high melting point.

• Because it is soluble in water.

What suffix is used when naming the oxygen part of CuO?

• ous

• ide

• ite

• ate

Why is it important to specify the charge of copper in CuO?

• Because copper is always positively charged.

• Because copper is a non-metal.
