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.
An international research team has succeeded in gaining new insights into the chemical properties of the superheavy element flerovium — element 114 — at the accelerator facilities of the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt. The measurements show that flerovium is the most vola more
In the 1860s, the chemists, Lothar Meyer and Dmitri Mendeleev, independently presented the first periodic system. Since then, the well-known tabular arrangement of the elements has been the guiding principle of chemistry. A team of researchers from the Max Planck Institute for Mathematics in the Sci more
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 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

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
For elements discovered more recently, a catalogue of names have been seriously and not-so-seriously suggested before the official names were confirmed. Past elements, too, have been subject to naming variations, be it due to simultaneous discoveries, language differences, or scientific squabbles ov more
Here’s a periodic table that’s crammed with data. It includes the melting point, boiling point, density, electronegativity, radius, and first ionisation energy of each element in the table. It’s also colour-coded to show how these properties vary from element to element. 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
