The Periodic Table of the Elements is a wonderful aid in understanding chemistry, if you understand the reasons the elements are sorted the way they are. The table itself is a model of information ...

150 years ago, Russian chemist Dmitrii Mendeleev created the periodic table of the elements, revolutionizing chemistry.

Researchers may have found a way to create a new superheavy element, known as "element 120," which would be so hefty that it would need to be put in a new row on the periodic table of elements. If ...

A new version of the periodic table of elements has predicted hundreds of highly charged ions that could be used to create the next generation of optical atomic clocks. The periodic table, first ...

I'm blogging about the periodic table this month in conjunction with my new book, The Disappearing Spoon: And Other True Tales of Madness, Love, and the History of the World From the Periodic ...

It's been almost two years since I've done a roundup of periodic tables (and six years since I posted the first one). Oh, you know the periodic table of elements; you may have even studied it. But ...

Well firework colors are created by using a variety of different elements found on the periodic table, with some elements ...

The organization of the periodic table reveals an element’s behaviors and characteristics: from atomic size, density and abundance, to how it would likely interact with others.

Accompanying Lesson Plan: Lesson 3.2: Finding Volume—The Water Displacement Method The chart shows that atomic size and mass for the first 20 elements in the periodic table. The size of the atoms and ...

The periodic table may be one of the greatest accomplishments in information visualization. Its simple approach–lining and layering atoms by number of protons–is something that anyone can ...

Here we have the periodic table showing only the valence, or outer electrons in each element. It is these outermost electrons that determine an element’s reactivity. Some patterns should stand out.
