One of the proud achievements of Oak Ridge National Laboratory is the discovery of three elements either by its own staff or in collaboration with other institutions in the United States and Russia.

The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

That’s why this periodic table clock really caught our eye. [gocivici]’s idea is a simple one: light up three different elements with three different colors for hours, minutes, and seconds ...

More than 75 years after its initial discovery, scientists have created an organometallic molecule containing the ...

This is the second part of a three-part series written by Carolyn Krause. Many of the elements were synthesized using an Oak ...

Scientists have found that our bodies need 28 different elements to function properly. These are almost one-quarter of the periodic table and are mainly found in the first four periods.

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 ...

The periodic table's most electronegative element is fluorine (3.98 on the Pauling scale and top right in the periodic table). The least electronegative element is cesium (0.79 on the Pauling scale ...

and all the elements in group 0 are unreactive non-metals. The zigzag, staircase, line in the diagram of the periodic table above separates the metals, on the left, from non-metals, on the right.

In 1862, French geologist Alexandre-Emile Beguyer de Chancourtois developed the 'telluric screw' – a three-dimensional arrangement ... their own versions of a periodic table. Meyer’s table was ...
