Why is it important to know common oxidation states?
• What happens when iron rusts?– List some ideas using your monatomic list.
Iron Rusting
Fe is oxidation state 0
Fe2+ is oxidation state of 2+
A pit is formed in the Fe. Water enters the pit.
Fe2+ and Fe3+ is exposed to oxygen and forms Fe2O3 with water attached.

Memorizing Monatomic Ions
• Recall the number in a series that you are able to remember in short term memory from the sequencing lab.
• Use this number and chunking when you study the monatomic ions to memorize these ions.
• This presentation will give you large chunks, but you may have to break them down into smaller chunks for your span.
Hopefully, your brain is a little larger than this one.
His sequence recall is less than one.

Variable Monatomic Ions• The transition monatomic ions have many
different oxidation charges (charge of the ion)• Many variable monatomic ions have common
names as well as the stock system name.• Learning the ions is difficult. Using your
chunking skills makes it much easier to memorize.
• There are many variable ion in the transition metals.
• The ions that are presented are only the common variable ions with common names.
The Stock system name uses Roman numerals for the charge of the ion.

Common Naming System• According to IUPAC
naming compounds with common names is typically used when the ion does not have more than two oxidation states.

Some words to remember for common naming
• -ous is less – The charge of the ion is the lower oxidation
number– Example Ferrous is Fe2+
• -ic is more– The charge of the ion is the higher oxidation
number– Example Ferric is Fe3+
