With yesterday’s announcement of the proposed names for the periodic table’s four newest members, the periodic table of elements will soon have a completed seventh period. This graphic, featured in The Conversation, and produced in collaboration with Professor Mark Lorch of the University of Hull, takes a look at the origins of the names of all 118 elements!
Extremium, catium, cyclonium and pandemonium: elements that you won’t find in the periodic table in classrooms and laboratories. However, they’re all names that have been suggested but rejected for elements in years gone by. This table takes a look at some of the different names that have been suggested or used in the past for various elements; below, we examine their origins, and the reasons for their rejection.
There are a whole host of periodic tables out there, and I’ve already added to the pile with a periodic table of data previously. Today’s post is another variation on the theme: a periodic table showing the possible and common oxidation states of every element. I was looking for one of these last week, out of interest, and couldn’t find one that presented the information in an easy-to-comprehend manner. To try to solve that, I made the table you can see at the top of the post here.
We’re all familiar with the periodic table, but the majority of non-chemists probably aren’t familiar with the everyday uses of some of the many elements it contains. Some elements that many haven’t heard of find uses in technologies or applications we take for granted – but the supplies of these elements on Earth are not infinite. Today’s graphic, in a collaboration with the American Chemical Society’s Green Chemistry Institute, looks at some of the endangered elements in the periodic table, and why we might miss them when they’re gone.
