The correct name of the example is iron(III) oxide. Example #4: name this compound: SnO. 1  First symbol is Sn, so the first part of the name is tin. 2  The Roman numeral is II, because one oxygen = -2, so the one tin equals +2. 3  Second element is oxygen (from the symbol O), so the name is ox + ide = oxide.

The North American craton is the bedrock forming the heart of the North American continent and the Canadian Shield is the largest exposed part of the craton's bedrock. The Canadian Shield is part of an ancient continent called Arctica, which was formed about 2.5 billion years ago during the Neoarchean era.It was split into Greenland, Laurentia, Scotland, Siberia, and East Antarctica and is now roughly situated in the Arctic around the current North Pole.he lowlands of the Canadian Shield have a very dense soil that is not suitable for forestation, but it also contains many marshes and bogs. The rest of the region has coarse soil that does not retain moisture well and is frozen with permafrost year round. Forests are not as dense in the north.
