Eric Scerri, a UCLA chemistry lecturer, has written at least six books discussing the orientation of the periodic table. His office is cluttered with posters and three-dimensional models of different ...

The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

The periodic table isn’t just a list of elements—it’s a map of predictable patterns called periodic trends. These trends, like atomic radius, electronegativity, and ionization energy, help scientists ...

Does your love of the periodic table extend to tying 200,000 tiny knots? That was the project that Jane Stewart of Surrey, England, undertook last summer. To honor the International Year of the ...

LET’S hear it for Dmitri Mendeleev. His periodic table has done a remarkable job of making sense of the elements, arranging them neatly into families whose members share similar properties. For more ...

The news broke that a railroad car, loaded with pure sodium, had just derailed and was spilling its contents. A television reporter called me for an explanation of why firefighters were not allowed to ...

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 ...
