The main reason for the molecule falling apart is that a lot of the heavier elements are not stable. Oganesson, which is number 118, has a half-life of 0.7 milliseconds. Number 116, livermorium ...

The periodic table organizes chemical elements based on atomic weight, electron configurations, and chemical properties, ...

The periodic table of elements (often known simply as the periodic table) has been helping scientists with their work for a little over 150 years. The handy visual reference guide organizes known ...

In addition, Moseley's laws allow us to calculate very accurately the wave-lengths of the X-ray spectral lines for any element in the periodic table, if those of the elements in its neighbourhood ...

Once created, element 119 will contain 119 protons—the most of any element discovered. It will sit on a new, eighth row of the periodic table, and it could be the first element to be named since 2016.

What are Endangered & Critical Elements? Of the 118 elements that make up everything—from the compounds in a chemist’s arsenal to consumer products on the shelf—44 will face supply limitations in the ...

Group 7 of the periodic table is something of an oddity. When the first periodic table was formulated by Mendeleev, it was the only group that contained just a single known element — manganese ...

From this scale and a new compilation of work function data, a linear equation is obtained which includes a parameter for any given element, depending on its subgroup in the periodic table. Data are ...

Eleven non-metals are gases at room temperature, including oxygen and chlorine. One non-metal, bromine, is a liquid at room temperature. The other non-metals are solids at room temperature ...

Silicon (Si) is a metalloid, element number 14 on the periodic table. Like carbon, silicon has four bonding sites, but silicon is more than twice as heavy as carbon. The high melting point of ...

We present a general method for solving the modified Helmholtz equation without shape approximation for an arbitrary periodic charge distribution, whose solution is known as the Yukawa potential or ...
