Naming Ionic Compounds and Charges

The video tutorial explains the naming conventions for ionic compounds in chemistry. It begins with an introduction to ionic and molecular compounds, followed by a detailed explanation of how to name binary ionic compounds. The tutorial distinguishes between type one and type two cations, providing rules and examples for naming compounds with each type. Type one cations have a fixed charge, while type two cations can have variable charges, requiring the use of Roman numerals to indicate the charge in the compound's name.

What are the two main types of compounds discussed in the video?

• Covalent and metallic compounds

• Molecular and metallic compounds

• Ionic and molecular compounds

• Ionic and covalent compounds

When naming binary ionic compounds with type one cations, what suffix is added to the anion?

• -ite

• -ate

• -ous

• -ide

Which of the following is an example of a binary ionic compound with a type one cation?

• Lead(II) chloride

• Sodium chloride

• Copper(I) chloride

• Iron(III) oxide

How do you indicate the charge of a type two cation in the name of a compound?

• By using a prefix

• By using a subscript

• By using a suffix

• By using a Roman numeral

What is the correct name for a compound with manganese(3+) and oxide ions?

• Manganese(II) oxide

• Manganese(III) oxide

• Manganese(IV) oxide

• Manganese oxide

Why is copper(I) chloride named with a '1'?

• Because copper has a charge of 1+

• Because chlorine has a charge of -1

• Because chlorine has a charge of -2

• Because copper has a charge of 2+

What is the charge of iron in iron(III) oxide?

• 3+

• 1+

• 2+

• 4+

In mercury(II) oxide, what is the charge of the mercury cation?

• 1+

• 4+

• 2+

• 3+

What is the correct name for a compound with lead(2+) and chloride ions?

• Lead(IV) chloride

• Lead(II) chloride

• Lead(III) chloride

• Lead chloride

Why is it important to specify the charge of a type two cation in a compound's name?

• To differentiate between different compounds

• To ensure the compound is neutral

• To show the compound's color

• To indicate the number of atoms
