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 ...

These rules help in identifying and writing chemical symbols consistently across all elements. The symbol serves as a shorthand notation for each element's name in formulas and equations, making ...

The periodic table stares down from the walls of just about every chemistry lab. The credit for its creation generally goes to Dimitri Mendeleev, a Russian chemist who in 1869 wrote out the known ...

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 ...

But the periodic table didn’t actually start with Mendeleev. Many had tinkered with arranging the elements. Decades before, chemist John Dalton tried to create a table as well as some rather ...

Michael R. Topp, professor of chemistry at the University of Pennsylvania, explains. Although some of the symbols on the periodic table may seem strange, they all make sense with a little background ...

Today augmented-reality startup Daqri unveiled Elements 4D, a set of interactive blocks that aims to help students learn the properties of hydrogen and oxygen in a more visual, educational, and ...

High school chemistry students will now have to learn about four additional elements on the Periodic Table of Elements. The International Union of Pure and Applied Chemistry (IUPAC) has announced the ...

Brian Resnick was Vox’s science and health editor and is the co-creator of Unexplainable, Vox’s podcast about unanswered questions in science. After months of suspense, the International Union of Pure ...
