The periodic table went through its entirety in 2016. The elements of the atomic numbers up to 118 have been discovered or produced. Initially used for the prediction of elements, today it is impossible to imagine a laboratory without it. The fathers of the proper rendering of the known elements Dmitri I. Mendeleev and J. Lothar Meyer brought joy and suffering to generations of prospective scientists with their listing of the known elements. This year is under the badge of this discovery.
Many students, especially non-science majors, dread chemistry. The first lesson in an introductory chemistry course typically deals with how to interpret the periodic table of elements, but its complexity can be overwhelming to students with little or no previous exposure. Now, researchers reporting more
The electronic structure of nonmagnetic crystals can be classified by complete theories of band topology, reminiscent of a “topological periodic table.” However, such a classification for magnetic materials has so far been elusive, and hence very few magnetic topological materials have been discover more
In the periodic table of elements there is one golden rule for carbon, oxygen, and other light elements. Under high pressures they have similar structures to heavier elements in the same group of elements. Only nitrogen always seemed unwilling to toe the line. However, high-pressure researchers of t more
The International Union of Pure and Applied Chemistry (IUPAC) Inorganic Chemistry Division has published a Provisional Recommendation for the names and symbols of the recently discovered superheavy elements 113, 115, 117, and 118. Tennessine (Ts) is proposed for element 117, recognizing the cont ... more
Join a guided tour of science’s most iconic image with chemical physicist and material scientist Jamie Gallagher, geek songstress Helen Arney and nanoscientist Suze Kundu. more
With four new element names officially confirmed last week, it’s past time the Compound Interest Periodic Table of Data was updated to include them! Here’s the updated table with nihonium, moscovium, tennessine and oganesson in their rightful places; the version above has a key denoting the differen more
This graphic looks at the discovery dates of the elements, as well as the countries in which they were discovered, and plots them all on a timeline to give some idea of the order of discovery. more
The periodic table has actually only just been ‘completed’ in the past year. Four new elements had their discoveries and names confirmed in 2016, and replaced the last few placeholder positions in the table. I say ‘completed’ because scientists are still trying to create elements beyond element 118, more
The clinical success of the platinum-based chemotherapeutic agents has prompted the investigation of coordination and organometallic complexes of alternative metal centers for use as anticancer agents. Among these alternatives, the third row transition metal neighbors of platinum on the periodic tab more
Studies on layered transition metal dichalcogenides (TMDs), in particular for Group VIB TMDs like MoS2 and WS2, have long reached a crescendo in the realms of electrochemical applications initiated by their remarkable catalytic and electronic properties. One area that garnered considerable attention more
Porphyrins are large π-aromatic systems that can complex metal ions from all across the periodic table. The resulting metalloporphyrins are readily tunable with regards to analyte detection properties, and constitute an important class of chemical sensors. In light of the current geopolitical situat more
Periodic table The periodic table of the chemical elements is a tabular method of displaying the chemical element s. Although precursors to this table exist, its invention is generally credited to Russia n chemist Dmitri Mendeleev in 1869. ... more
