© Copyright Pearson Prentice Hall Slide 2 of 33 Naming Ions > Monatomic Ions The charges of the cations of many transition metal ions must be determined from the number of electrons lost.
Slide 3 of 33 © Copyright Pearson Prentice Hall Naming Ions > Monatomic Ions These colorful solutions contain the transition metal ions Co 3+, Cr 3+, Fe 3+, Ni 2+, and Mn 2+.
Slide 4 of 33 © Copyright Pearson Prentice Hall Naming Ions > Monatomic Ions Two methods are used to name the ions of transition metals. The Stock system The classical method
Slide 5 of 33 © Copyright Pearson Prentice Hall Naming Ions > Monatomic Ions In the Stock system, a Roman numeral in parentheses is placed after the name of the element to indicate the numerical value of the charge.
Slide 6 of 33 © Copyright Pearson Prentice Hall Naming Ions > Monatomic Ions In an older less, useful method, the classical name of the element is used to form the root name for the element.
