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 ...

Scientists in Japan think they've finally created the elusive element 113, one of the missing items on the periodic table of elements. Element 113 is an atom with 113 protons in its nucleus — a type ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The Christian Science Church, and we’ve always been transparent about that. The Church publishes the Monitor ...

When the International Union of Pure and Applied Chemistry named element 118 in honour of nuclear physicist Yuri Oganessian, it was continuing a long but fractious tradition. Only 17 people have been ...

A new chart for highly charged ions (HCIs) has been proposed, aiming to replicate the conventional periodic table’s ...

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 periodic table is one of the triumphs of science. Even before certain elements had been discovered, this chart could successfully predict their masses, densities, how they would link up with other ...

They exist for only seconds at most in real life, but they've gained immortality in chemistry: Two new elements have been added to the periodic table. The elements were recognized by an international ...

The classic design of the table was created by Dmitri Mendeleev in 1863, organizing the then-known elements by number of electrons. Inspired by a graphic that sized the elements to reflect their ...

Measurements of an artificial radioactive element called lawrencium could revive an arcane controversy over the element’s position in the periodic table — and the structure of the table itself. An ...

GALLIUM IS an unusual element. It is a light, silvery metal, similar to aluminium. But unlike aluminium, if you hit it with a hammer it shatters like glass. It melts at about 30°C—in your hand, or ...
