Worksheet - Ionic Nomenclature

40. Write this in your notes
Latin Names
Some compounds were given Latin names before systematic nomenclature was created
These are still in use even today
On cations with two primary oxidation states, a suffix indicates the oxidation state
suffix "–ic" means higher oxidation state
suffix "–ous" means lower oxidation state
Most often used on elements with Latin names

41. Example of Latin Name In Latin, iron is called ferrum
This is why its atomic symbol is Fe
Iron has two primary oxidation states, +3 and +2
Fe+3 is called ferric
Fe+2 is called ferrous

42. What is this called?
A ferrous wheel!!!

43. Example of Latin Name
In each oxidation state, Fe can be combined with O
Fe2O3 is ferric oxide
FeO is ferrous oxide

44. Latin Names
Latin names are most frequently used with iron, copper, tin and lead, but can be used with any element
Systematic Name
Latin Name
iron (III) oxide
ferric oxide
iron (II) oxide
ferrous oxide
copper (II) oxide
cupric oxide
copper (I) oxide
cuprous oxide
tin (IV) oxide
stannic oxide
tin (II) oxide
stannous oxide
lead (IV) oxide
plumbic oxide
lead (II) oxide
plumbous oxide
