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.
After a suggestion over on the facebook page for the site, I decided to make some fill-in-the-blanks style teaching versions of the element infographics for teachers. These could be used as part of a research task on the different groups of elements in the Periodic Table. There’s a sheet for each of the groups, and you can download all of them in a zip file here. Feedback appreciated!
