Since the elements are produced in extremely small quantities (a few atoms in many cases), it is difficult to confirm the stability of most of these elements. If the half-lives are as long as predicted (region of stability), and there are sufficient yields, there are exciting possibilities ...
It is likely that the heavy elements may also have multiple oxidation states. In this context, 10–100 atoms of the super-heavy species are needed depending on the half-life. If, on the other hand, we are limited to a few atoms of these super-heavy species, it is likely that any ...

The two as yet unnamed new elements, currently going by ununquadium and ununhexium, are now the two heaviest elements on the table (289 and 292 atomic mass, respectively) and both are highly radioactive. 114 had several groups which claimed to have produced it in a lab, but just two...

It is amazing to think that everything around us is made up from just 90 building blocks – the naturally occurring chemical elements. Dmitri Mendeleev put the 63 of these known at the time into order and published his first version of what we now recogn
Let’s first consider how the periodic table was developed. By the late 18th century, chemists were clear about the difference between an element and a compound: elements were chemically indivisible (examples are hydrogen, oxygen) whereas compounds consisted of two or more elements in combina...
The MFS model is directly applied in partially saturated reservoir rocks, where the gas–water mixture is obtained with the Wood equation (there are no gas pockets), and the properties are listed in Table 1. The numerical examples of the characteristics of wave prorogation by the proposed model...
