With element 117, the periodic table is complete for the first time ... Seaborgium (106) and bohrium (107) seemed to act just the way Mendeleev would have guessed, inspiring researchers to ...

The new element is approximately 277 times heavier than hydrogen, making it the heaviest element in the periodic table ... element 107 is called Bohrium, element 108 Hassium, element 109 ...

The German team identified six nuclei of the element. [See Periodic Table of the Elements] There are 10 isotopes of bohrium with known half-lives. The most stable is 270 Bh, which has a half-life ...

Bohrium, the name given to element 107 ... is said to have invoked relativity to predict the end of the periodic table at element 137. To Feynman, 137 was a “magic number”—it had popped ...

A new element may soon join the periodic table: an international team of researchers ... elements by loading on extra protons, including Bohrium, Hassium, Roentgenium, Darmstadtium and Copernicium.

At the far end of the periodic table is a realm where nothing is quite as it should be. The elements here, starting at atomic number 104 (rutherfordium), have never been found in nature.

A new study lays the groundwork to expand the periodic table with a search for element 120, to be made by slamming electrically charged titanium atoms, or ions, into a californium target.
