Astronomers from the University of Turku in Finland and elsewhere have performed a broadband spectral and timing study of an ...

Using the Hard X-ray Modulation Telescope (HXMT), Chinese astronomers have observed an X-ray binary system designated IGR J19294+1816. As a result, they discovered multiple X-ray quasi-periodic ...

The periodic table of elements, or Mendeleev’s table, was created in 1869 by Russian chemist Dmitri Mendeleev. This table organizes all known chemical elements by their atomic number, or the ...

The periodic table is one of the greatest achievements in scientific history, a tool that has transformed chemistry from an ...

MIT researchers have created a periodic table that orders AI algorithms based on the properties they share with a mathematical framework known as information contrastive learning (I-Con).

The periodic table, first invented by Dmitri Mendeleev in 1869, groups the 118 known chemical elements according to their chemical properties.

Discover the history, structure, and importance of the periodic table of elements, from Mendeleev’s discovery to modern scientific applications.

History of Periodic Table of Elements Johann Dobereiner, a German chemist, was the first to consider trends among element properties in the early 1800s.

These are the superheavy elements: after rutherfordium come dubnium, seaborgium, bohrium, and other oddities, all the way up to the heaviest element ever created, oganesson, element 118. Humans ...

Since the turn of the century, six new chemical elements have been discovered and subsequently added to the periodic table of elements, the very icon of chemistry. These new elements have high ...

Naturally occurring superheavy elements beyond those listed in the periodic table could potentially explain why asteroid 33 Polyhymnia is so dense, new research suggests.
