Heavy water is a form of water with a unique atomic structure and properties coveted ... help keep such a chain reaction going. As each uranium atom breaks apart, it shoots out neutrons that ...

It features a berkelium atom sandwiched between two eight-membered carbon rings. This symmetrical structure was confirmed ...

They began to suspect that Fermi hadn't created a new element at all but might have actually split the uranium atom in two -- at that point a barely imaginable event. Before they could confirm ...
