Their former colleague Lise Meitner, who a few months before had been forced to flee Germany and seek refuge in Sweden, and her nephew Otto Frisch realized that the uranium nucleus had split in two.

When atomic bombs struck Hiroshima and Nagasaki in 1945, the blinding light and heat from the explosions left only shadows of ...

Uranium is the primary fuel for nuclear reactors and must be managed properly, in a safe and sustainable manner. Recent annual production of natural uranium world-wide has been between 55,000 and ...

Meitner wrote back explaining that the uranium nucleus was splitting into two roughly equal parts. She called the process “fission”. The next piece of the puzzle came when Italian physicist ...

In ordinary water, each hydrogen atom has just a single proton in its nucleus. In heavy water ... harness the energy of countless atoms of uranium splitting apart, or fissioning, in a chain ...

Low Enriched Uranium (LEU) is the basic material to fabricate nuclear fuel. It consists of uranium hexafluoride that is a white-grey, waxy solid at standard temperature and pressure. LEU is made by ...

a few of the neutrons bombarding the uranium nucleus should cause it to fission and the telltale outcome would be a small but measurable amount of the element barium. After an hour, Jim switched ...

Elements - the basic building blocks of chemistry, like hydrogen, oxygen, and uranium - are made up of single atoms. Atoms in turn, are made of a nucleus containing protons and neutrons ...
