Xenon on the periodic table of the elements. Noble gas with the atomic number 54 and symbol Xe from Greek xenon, meaning foreign. Used in lamps, as anesthetic and neutron absorber in nuclear reactors.

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

In the Introductory Seminar CHEM 29N: "Chemistry in the Kitchen" students learn about the chemical makeup of food.

Ivan Dmochowski ponders how xenon, though initially slow to earn a spot in the periodic table, is now at the forefront of advances in science and technology. For all their nobility, elements of ...

The periodic table - AQA Mendeleev made an early periodic table. In the modern periodic table, elements are in order of atomic number in periods and groups. Electronic structures model how ...

A breakthrough in heavy-element chemistry shatters long-held assumptions about transuranium elements. Researchers have ...

The pioneering nuclear chemist Glenn Seaborg discovered berkelium at Berkeley Lab in 1949. It was one of many achievements related to transuranium elements that led to his winning the 1951 Nobel Prize ...

Scientists have discovered “berkelocene,” the first organometallic molecule to be characterized containing the heavy element berkelium. The breakthrough disrupts long-held theories about the chemistry ...
