The periodic table of elements is a landmark categorization developed in 1869 by the Russian chemist and inventor Dmitri Mendeleev. It arranges all natural and synthetic elements by their atomic ...

This year marks the 150th anniversary of the publication of Mendeleev’s Periodic Table of Chemical Elements in 1869. In celebration, the United Nations Educational, Scientific, and Cultural ...

Mendeleev’s periodic table, published in 1869, was a vertical chart that organized 63 known elements by atomic weight. This arrangement placed elements with similar properties into horizontal rows.

So the beauty of the periodic table is that the elements that are in columns, up and down, have similar properties. But there are similarities within a group going across too.

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 ...

Why has the periodic table endured for 150 years? It’s an amazing tool that can compress a huge amount of information into one format. It’s one of the first things people learn about chemistry.
