Type 2 Ionic Compounds and Naming

The video tutorial explains how to identify and name Type 2 ionic compounds, focusing on transition metals that can form multiple cations. It provides examples, such as CuCl2 and Fe2O3, to demonstrate the naming process using Roman numerals to indicate the charge of the metal. The tutorial also covers how to write formulas from compound names and how to identify Type 2 compounds by looking for transition metals with multiple charges.

What distinguishes a Type 2 ionic compound from a Type 1?

• Type 2 compounds have metals that can form multiple charges.

• Type 2 compounds involve nonmetals only.

• Type 2 compounds do not involve transition metals.

• Type 2 compounds are always gases.

How do you determine the charge of copper in CuCl2?

• By checking the charge of the anion and balancing it.

• By looking at the color of the compound.

• By counting the number of copper atoms.

• By measuring the mass of the compound.

What is the correct name for Fe2O3 using Type 2 naming conventions?

• Iron trioxide

• Iron(III) oxide

• Iron(II) oxide

• Iron oxide

When given the name 'cobalt(III) sulfide', how do you write its formula?

• CoS

• Co2S3

• Co3S2

• CoS3

What is the formula for manganese(IV) oxide?

• MnO

• MnO2

• Mn2O3

• Mn2O4

How can you identify a Type 2 compound from its name?

• It contains a metal with a fixed charge.

• It includes Roman numerals indicating the metal's charge.

• It is always a binary compound.

• It contains only nonmetals.

Which of the following is a Type 2 compound?

• Cu2S

• KBr

Why is zinc not considered a Type 2 compound?

• It always forms a +2 charge.

• It forms multiple charges.

• It is not a transition metal.

• It is a nonmetal.

What is the charge of tin in SnSO4?

• +1

• +2

• +3

• +4

Which of the following metals always forms a single charge?

• Silver

• Iron
