Did you know

There are elements that be stopped? Yes ... .. if compararmos a current table with the end of the twentieth century, we see some differences. It seems logical to think that in the old tables do not appear chemical elements that had not been discovered, but not so logical that include some elements that are not today. What happens? The answer is often considered a new element to what was a mixture of both. Thus, for example, early nineteenth century it was observed that along with the cerium was found two new elements to which Latane and didymium name. It was not until the end of the century when it was discovered that the item didymium was actually a mixture of two elements praseodymium and neodymium. He has been in history as more than 100 elemntos didymium have ceased to be.
You know the origin of the symbols of the elements? Most of the symbols of the elements derived from their original Latin names, and even more modern elements, discovered in the U.S. or Europe, have been given Latin names of termination, with a prefix in honor of a scientist or where they were found. As the Spanish a Latin root language, most of the symbols match the initials of the element.However, there are certain elements whose Latin or Greek names do not match with the Spanish, and hence has symbols that bear no relationship to the Castilian name of the item. "IUPAC? The nomenclature of the IUPAC (international union d Pure and Applied Chemistry) numbers to groups of 1 to 18. The elements of groups 3 to 12, in the center, are called TRANSITION elements.
