Nearly 300 years later, some chemists thought they’d achieved this transformation. When in 1900 Ernest Rutherford and Frederick Soddy, working at McGill University in Montreal, figured ...

13 de may. de 2024 · Rutherford fue galardonado con el Nobel de Química en 1908, pero sus trabajos abrieron paso a otros avances relevantes como el descubrimiento de los isótopos por parte de Frederick Soddy (su discípulo), galardonado por el Nobel en 1921, y también al hallazgo en 1932 del neutrón, que condujo directamente a la fisión nuclear y a ...
28 de abr. de 2024 · Frederick Soddy (1913) acuñó el término "isótopo" para describir diferentes átomos de un mismo elemento que tienen el mismo número de protones en el núcleo (y, por lo tanto, el mismo número atómico), pero difieren en el número de neutrones (y, por lo tanto, en el número másico).
29 de abr. de 2024 · September 1902 Ernest Rutherford and Frederick Soddy published their theory of radioactive decay in the Philosophical Magazine. They discovered that radioactive material decayed according to an exponential law and created the concept of half-life.
10 de may. de 2024 · Hardy’s friend and Oxford colleague Frederic Soddy, a 1921 Nobel laureate in chemistry, called the discussion in the Apology “cloistral clowning" [7, p. 3]. Another friend and Cambridge colleague, Norbert Wiener, sometimes referred to as the father of cybernetics, confessed [ 1 , p. 158]:
9 de may. de 2024 · When Ernest Rutherford and Frederick Soddy found similar decay and regeneration in thorium X and thorium, they were led to the transformation theory of radioactivity, which explained the phenomenon as a subatomic chemical change in which one element spontaneously transmutes into another.
