Physicists have filled in some longtime blank spaces on the periodic table, calculating electron affinities of the lanthanides, a series of 15 elements known as rare earths. Physicists at Michigan ...

Last week, we explored the evolution of the periodic table, with all its elements in order. Now that we’re well-organized, let’s dive into the reasoning. * The table is generally sorted by the number ...

We explore the science and chemistry going on inside Theo Gray's periodic table table. Step into his office, and you'll see a silicon disc engraved with Homer Simpson, a jar of mercury, uranium shells ...

RUN your fingers over the white keys of a piano. The notes get higher and higher as your hand moves to the right. On the eighth key, something beautiful happens: a note hangs in the air that embodies ...

Posters in chemistry labs are in need of an update. The periodic table now has four new elements, completing its seventh row. The International Union of Pure and Applied Chemistry (IUPAC) and the ...

The iconic chart of elements has served chemistry well for 150 years. But it’s not the only option out there, and scientists are pushing its limits. By Siobhan Roberts When Sir Martyn Poliakoff, a ...

One hundred fifty years after Russian chemist Dmitri Mendeleev published his system for neatly arranging the elements, the periodic table it gave birth to hangs in every chemistry classroom in the ...

As of 2019, the Periodic Table of the Elements has been around for 150 years. Maybe you've felt a certain chemistry with 2019 but don't know why? Maybe it's because this year marks the 150th ...

The periodic table of the chemical elements is a tabular method of displaying the chemical elements, first devised in 1869 by the Russian chemist Dimitri Mendeleev. Mendeleev intended the table to ...

Theo Gray collects elements and has put together this awesome Periodic Table Table. This week Reactions explores the science and chemistry going on inside this periodic table. Step into his office, ...

The periodic table, also called the periodic table of elements, is an organized arrangement of the 118 known chemical elements. The chemical elements are arranged from left to right and top to bottom ...
