Naming and Identifying Compounds

Mrs. Thompson explains the complexities of naming mixed compounds, including ionic, covalent, and acidic types. She introduces a flowchart to aid in the naming process and discusses the importance of identifying the starting element to determine the correct naming system. The video covers common mistakes in naming, such as forgetting Roman numerals and misusing prefixes. Examples are provided to illustrate the naming process, emphasizing the need to understand charges and bonding types. The session concludes with practice exercises to reinforce learning.

What is the first step in identifying the type of compound you are dealing with?

• Determine if it starts with hydrogen

• See if it ends with a non-metal

• Identify if it has a polyatomic ion

• Check if it contains a metal

Which of the following is a characteristic of ionic compounds?

What is a common mistake when naming ionic compounds?

• Forgetting to use prefixes

• Using the wrong common name

• Changing the subscripts of polyatomic ions
