The periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to Dmitri Mendeleev and Lothar Meyer and the ...

Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...

The periodic table of chemical elements hangs in front of chemistry classrooms worldwide and is an icon for science. Yet much was unknown about its history -- until now. The periodic table reflects ...

The periodic table of the elements, principally created by the Russian chemist, Dmitry Mendeleev (1834-1907), celebrated its 150th anniversary last year. It would be hard to overstate its importance ...

The United Nations have proclaimed 2019 to be the International Year of the Periodic Table of Chemical Elements (IYPT 2019) to mark the 150th anniversary of the classification system that decorates ...

In the 1860s, the chemists, Lothar Meyer and Dmitri Mendeleev, independently presented the first periodic system. Since then, the well-known tabular arrangement of the elements has been the guiding ...

Could atomically precise nanoclusters mimic the chemistry of particular atoms without their toxic or cost drawbacks? James ...

This year marks the 150th anniversary of the Periodic Table, and the principles that drove Dmitri Mendeleev to construct his table are still influencing today's research advances. This year marks the ...

Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

Wow! The International Year of the Periodic Table started with a bang at C&EN. There is already so much activity surrounding IYPT that we can hardly contain our excitement. There is no doubt that 2019 ...

Eric Scerri's delightful "The Periodic Table: Its Story and Its Significance" follows the 1969 classic by J. W. Spronsen, "The Periodic System of Chemical Elements," but is a different treatment of ...
