Un aspecto especialmente útil (y fascinante) de este tipo de tablas, es que, si acertadas, pueden tener cierta capacidad predictiva (o ayudar a ello).<br />
<br />
<b>Elementos químicos</b>: el propio Mendeleev predijo 3 en 1871: <a href="https://en.wikipedia.org/wiki/Periodic_table#Mendeleev" title="en.wikipedia.org/wiki/Periodic_table#Mendeleev" rel="nofollow">en.wikipedia.org/wiki/Periodic_table#Mendeleev</a><br />
<i>In 1871, Mendeleev published a long article, including an updated form of his table, that made his predictions for unknown elements explicit. Mendeleev predicted the properties of three of these unknown elements in detail: as they would be missing heavier homologues of <b>boron, aluminium, and silicon</b>, he named them eka-boron, eka-aluminium, and eka-silicon (&#34;eka&#34; being Sanskrit for &#34;one&#34;).</i><br />
--&#62; <i>In 1875, the French chemist Paul-Émile Lecoq de Boisbaudran, working without knowledge of Mendeleev's prediction, discovered a new element in a sample of the mineral sphalerite, and named it gallium. He isolated the element and began determining its properties. Mendeleev, reading de Boisbaudran's publication, sent a letter claiming that gallium was his predicted eka-aluminium. Although Lecoq de Boisbaudran was initially sceptical, and suspected that Mendeleev was trying to take credit for his discovery, he later admitted that Mendeleev was correct.</i><br />
--&#62; <i>In 1879, the Swedish chemist Lars Fredrik Nilson discovered a new element, which he named scandium: it turned out to be eka-boron. </i><br />
--&#62; <i>In 1886 Eka-silicon was found by German chemist Clemens Winkler, who named it germanium. </i><br />
The properties of gallium, scandium, and germanium matched what Mendeleev had predicted.<br />
<br />
<b>Partículas elementales</b>: el física de partículas, organizarlas en distintas tablas o diagramas también ayudó a predecir algunas partículas (y sus propiedades) antes de su descubrimiento experimental:<br />
- <a href="https://en.wikipedia.org/wiki/Standard_Model#Tests_and_predictions" title="en.wikipedia.org/wiki/Standard_Model#Tests_and_predictions" rel="nofollow">en.wikipedia.org/wiki/Standard_Model#Tests_and_predictions</a>: <i>The Standard Model predicted the existence of the W and Z bosons, gluon, top quark and charm quark, and predicted many of their properties before these particles were observed. The predictions were experimentally confirmed with good precision.</i><br />
- <a href="https://es.wikipedia.org/wiki/Camino_óctuple_(física)" title="es.wikipedia.org/wiki/Camino_óctuple_(física)" rel="nofollow">es.wikipedia.org/wiki/Camino_óctuple_(física)</a>: <i>Además de organizar los mesones y los bariones de espín 1/2 en un octete, los principios del camino óctuple también se aplican a los bariones de espín 3/2, que forman un decuplete. Sin embargo, una de las partículas de este decuplete nunca se había observado anteriormente. Gell-Mann llamó a esta partícula Ω− y predijo en 1962 que tendría extrañeza −3, carga eléctrica −1 y una masa cercana a 1680 MeV/c2. En 1964, un grupo del acelerador de partículas en Brookhaven descubrió una partícula de características muy próximas a estas predicciones. Gell-Mann recibió en 1969 el premio Nobel de Física por su trabajo en la teoría de partículas elementales.</i></p><p>&#187;&nbsp;autor: <strong>Hombre_de_Estado</strong></p>]]></description>
