Further data for naturally occuring isotopes of tungsten are listed above. This table gives information about someradiosotopesof tungsten, theirmasses, theirhalf-lives, theirmodes of decay, theirnuclear spins, and theirnuclear magnetic moments. ...
As can be seen from the above, due to the marginally higher half-life of Bh, some experiments could be carried out to find out about the chemical nature of the element. Since the elements are produced in extremely small quantities (a few atoms in many cases), it is difficult to confirm...
Chemistry teachers recently had to update their classroom décor, with the announcement that scientists have confirmed thediscovery of four new elementson the periodic table. The as-yet unnamed elements 113, 115, 117 and 118 filled in the remaining gaps at the bottom of the famous chart—a road...
The standard form of the periodic table shown here includes periods (shown horizontally) and groups (shown vertically). The properties of elements in groups are similar in some respects to each other. There is no one single or best structure for the periodic table but by whatever consensus ther...
The borders of the periodic table of the elements and of the chart of nuclides are not set in stone. The desire to explore the properties of atoms and their nuclei in a regime of very large numbers of electrons, protons and neutrons has motivated new experimental facilities to create new el...
His first table in 1869 wasn’t perfect. He produced another table in 1871 which had more spaces for undiscovered elements. There was also one big unresolved problem. There was a huge gap in atomic weights between the elements cerium and tantalum that he couldn’t resolve. ...
Currently, the periodic table is comprised of 116 elements, with scientists continuing to push its boundaries. Scerri notes, for instance, the recent addition of element 118 (the "atomic number," or number of protons in an atom's nucleus) to the periodic table by a team of Russian and ...

has spread to many stores in the field and still lives, spoken by people who are quite surprised if by chance they happen to find out that they are using Hebrew words. Some, for example, still use the expression na vesta a kinim to describe a polka-dot dress: now, kinim are lice,...
Like you, the elements have lives: personalities and attitudes, talents and shortcomings, stories rich with meaning. You may think of them as the inscrutable letters of the periodic table but you know them much better than you realise. Welcome to a dazzling tour through history and literature...
