Which element is synthetic?
There are a number of synthetic elements. And a few that are what is called quasi-synthetic. The synthetic ones aren't found in nature. And it could be said that the quasi-synthetic ones are found in nature in only the barest trace amounts. The nice folks at Wikipedia have posted a comprehensive list, and a link is provided. That way you can scan the list quickly, and you will have the added advantage of being able to link to any element that looks interesting. Yes, that's right. All the elements on the list are actually hyperlinks to the Wikipedia article on that element. How cool is that?!
