Oxidation for 8th grade science


 

Where can I find information on oxidation or metals for an eigth grade research paper?

Rust is an example of oxidation of iron or steel, Sarah. The white pitmarks you see on old aluminum is another example. The green color you see on bronze and brass statues is a third example. Basically, oxygen from the air combines with the metal to form a metal oxide. This happens to all metals except gold, which is why it is possible to find gold nuggests in nature, but you don't find nuggets of other metals, you only find 'ores' that have to be smelted down to remove the oxygen. Now you should have enough terms and concepts to start looking stuff up for a report. Good luck.
