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 ...

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 ...

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 ...

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 multinational team of scientists has isolated four new superheavy elements that sit at the very end of the periodic table, completing the seventh row. Share on Facebook (opens in a new window) Share ...

The periodic table is used in chemistry to organize different elements. Elements are atoms with a different number of protons and electrons. Protons are particles that are in center of the atom and ...

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 ...

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 ...
