古代的人们曾经梦想把一种元素转化成别种元素,他们梦想“点铁成金”,这就是古代所谓的“炼金术”。在科学发展的初期,还认为“炼金”只是术士们的空想,事实上那时候也没有成功,可是在今天却已经有了成为现实的可能。现在“点铁成金”虽然还没有实现,但是科学家们不但已经实现了元素间的转变,而且还制造出许多种地球上原来没有的新元素——超铀元素,也制造出许多种元素的放射性同位素。这些人造元素在科学上已经发生了重大的作用。例加:人造的超铀元素钚,已经在原子堆中应用,产生着原子能;各种放射性同位素在化学、生物学 People in ancient times once dreamed of transforming one element into another. They dreamed of “finishing iron into gold”. This was what was called “alchemy” in ancient times. In the early stages of scientific development, it was also believed that “Alchemy” was only a fantasy of warlocks. In fact, it was not successful at that time. However, today it has become possible. Now that “point iron has become a gold” has not yet been realized, scientists have not only achieved the transformation between elements, but also produced many new elements that are not present on Earth—trans-uranium elements, and also produced radioactive elements of many kinds of elements. isotope. These artificial elements have already played a major role in science. Addition: Man-made transuranic helium, which has been used in atom reactors to generate atomic energy; various radioisotopes in chemistry and biology
