Periodic table of the elements. All elements with atomic number Z greater than 83 are radioactive and have no stable isotopes. The elements 104, 105, and 106 have not yet been named. Element 101 (mendeleevium) is named for Dmitri Mendeléev. The underlying reason for the obvious regularity ...

Periodic Table of Elements Element Ytterbium - Yb Comprehensive data on the chemical element Ytterbium is provided on this page; including scores of properties, element names in many languages, most known nuclides of Ytterbium. Common chemical compounds are also provided for many elements. In ...
This table provided by us will have all the exact names along with the elements; besides this, the table will also have their IUPAC names in it. Many tables don’t provide the name and often students don’t understand which element has which name, this often leads to confusion and very ...
It was 3 years later that Coster and Hevesy reported the discovery of hafnium as the 72nd element. “Furthermore, we now know that, accordingly the Werner form of the periodic table, the rare-earth metals are consecutive members of the long cesium period and do not completely fall out of...
Short history of how the Periodic table of chemical elements was arranged, from Lavoisier's Table of simple substances to Seaborg Actinide concept.
(element 100), do not occur naturally in the Earth’s crust. To be studied, they thus have to be produced artificially. They bridge from the heaviest naturally occurring elements to the so-called superheavy elements, which start at element 104. Superheavy elements owe their existence t...

The most common form of the Periodic Table, the Mendeleev-Seaborg form, has the f- elements at the bottom. Fourteen f- block elements increase the period length to thirty-two. For nearly three centuries, a new element has been discovered every two and-one-half years, on average. ...
Element 111 has also been acknowledged by the joint IUPAC/IUPAP working party to have first been synthesized by the same German group at Darmstadt, but a name has not yet been suggested. It is shown on the table with its IUPAC provisional name and symbol “Uuu.” The elements with atomic...
