Naming and Charges of Ionic Compounds

This tutorial covers the naming of binary ionic compounds, focusing on both simple and transition metal compounds. It explains how to name cations and anions, including those with multiple charges, using Roman numerals for transition metals. The video provides examples and practice exercises to reinforce the concepts.

What is the primary focus when naming binary ionic compounds?

• Using prefixes for the number of ions

• Determining the molecular weight

• Naming the cation and anion

• Identifying the number of atoms

How do you name an anion in a binary ionic compound?

• Use a prefix to indicate charge

• Change the ending to 'ide'

• Add 'ate' to the end

• Keep the original name

What is the name of the compound with the formula Al2O3?

• Aluminum Dioxide

• Aluminum Oxide

• Aluminum Hydroxide

• Aluminum Trioxide

Why don't the names of ionic compounds depend on the number of each type of ion?

• Because the overall charge is neutral

• Because the names are based on molecular weight

• Because the names are based on the number of atoms

• Because the names are based on the color of the compound

What is the role of Roman numerals in naming ionic compounds with transition metals?

• To specify the compound's state

• To denote the compound's color

• To show the charge of the metal ion

• To indicate the number of atoms

In the compound CuCl2, what is the charge on the copper ion?

• +4

• +2

• +1

• +3

What is the name of the compound Fe2O3?

• Iron(II) Oxide

• Iron(IV) Oxide

• Iron(III) Oxide

• Iron(V) Oxide

How do you determine the charge of a transition metal in a compound?

• By measuring the compound's mass

• By ensuring the compound is neutral

• By using the periodic table

• By counting the number of atoms

What is the name of the compound MnO2?

• Manganese(IV) Oxide

• Manganese(III) Oxide

• Manganese(II) Oxide

• Manganese(V) Oxide

In the compound Cr2S3, what is the charge on each chromium ion?

• +1

• +2

• +3

• +4
