National Periodic Table Day – Six Different Periodic Tables!

February 7th, 2017|

Today, February 7, is National Periodic Table Day. You could be forgiven for not knowing – it was actually only ‘founded’ in May 2015, so this is only the second time it’s rolled around. February 7 was picked because it marks the date on which John Newlands’ first periodic table of elements was published way back in 1863. By happy coincidence it’s also only a day before the birthday of Dmitri Mendeleev, the scientist most famously associated with the periodic table.

The Compound Interest Periodic Table of Data – New Elements Update!

With four new element names officially confirmed last week, it’s past time the Compound Interest Periodic Table of Data was updated to include them! Here’s the updated table with nihonium, moscovium, tennessine and oganesson in their rightful places; the version above has a key denoting the different group names, but there’s also a version which denotes s, p, d and f block elements.

The Periodic Table of Elements: Element Name Origins

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!

A Periodic Table of Rejected Element Names

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.

The Periodic Table of Oxidation States

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.

The Periodic Table’s Endangered Elements

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.
