Ghiorso is awakened by the fire alarm, connected to the detector of the experiment for the creation of the first atom of element 101. That night the event will repeat itself another 16 times. After having already honored the state of California, and Berkeley, the Americans decide to dedicate 101 to a Russian, Mendeeleev. Mendeleevium is born. In the early 1960s, again in California, Nobelium (102) and lawrencium (103) will be synthesized. But then the Californian monopoly will end, and the next one (104 Rutherfordium) will be discovered in Dubna in Russia, and also the next one (105 Dubnium), while 106 (Seaborgium) will be discovered simultaneously by the Russians and Californians. The dispute will drag on until the 1990s, when the German group from Darmstadt will take the lead.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>California.
