Naming and Formulas of Ionic Compounds

This video tutorial by Mrs. Basen explains how to name ionic compounds with metals that have multiple charges. It covers the use of Roman numerals to specify the charge of the metal in the compound name, provides examples, and includes practice problems. The tutorial also explains how to write formulas for these compounds, emphasizing the importance of balancing charges to achieve neutrality.

What is the main difference in naming ionic compounds with multiple charge metals compared to single charge metals?

• The anion is named first.

• A Roman numeral is used to indicate the metal's charge.

• The compound name ends with 'ate'.

• The metal is always named last.

Which of the following is an example of the older naming system for iron with a +3 charge?

• Ferric

• Iron(III)

• Ferrous

• Iron(II)

How would you name the compound CuCl2 using the systematic naming method?

• Copper(II) chloride

• Copper(I) chloride

• Copper dichloride

• Copper chloride

What charge does iron have in the compound Fe2O3?

• III

What is the correct name for PbCl4?

• Lead dichloride

• Lead chloride

• Lead(IV) chloride

• Lead(II) chloride

How do you determine the charge of a metal in a compound when given the Roman numeral?

• By the color of the compound.

• By the Roman numeral itself.

• By the number of anions present.

• By using the periodic table.

What is the formula for a compound with cobalt(II) and chlorine?

• CoCl

• Co2Cl
