The periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to Dmitri Mendeleev and Lothar Meyer and the ...

Published: November 26, 2020 9:03am EST The periodic table of the elements, principally created by the Russian chemist, Dmitry Mendeleev (1834-1907), celebrated its 150th anniversary last year.

Elements with atomic numbers 113, 115, 117, and 118, have been added to the periodic table, according to the International Union of Pure and Applied Chemistry (IUPAC).

Today, the periodic table has 116 elements, the most recent of which was added just last month -- an element that for now is known as element 118 for the number of protons in its nucleus, more ...

Each area of the new table has been colour coded to indicate its vulnerability. In most cases, elements are not lost but, as we use them, they become dissipated and much less easy to recover.

After a 5-month review, the names of four new elements have been approved, so Nihonium, Moscovium, Tennessine, and Oganesson can now officially join the periodic table. The discovery of these ...

Interestingly, Janet also provided space for elements right up to number 120 despite only 92 being known at the time (we’re only at 118 now). Charles Janet’s left-step table. Wikipedia, CC BY-SA ...

The elements, discovered by researchers from Japan, Russia, and the United States, are known by their atomic numbers of 113, 115, 117, and 118. They will be given permanent names soon, according ...
