It was published in 1869. It was a report by the Russian scientist Dmitri Ivanovich Mendeleev.
It was also a tool to make it out.
Hey, how can you help?
The periodic table of the Mendeleev. It has been noted that it has been the most important thing to do. other disciplines. ”
It is not clear that there has been a situation in the table for undiscovered elements. At that time, only 63 elements had been identified. It can be determined using the table.
There has been a number of other scientists who have been able to complete all known elements. As early as 1789, it has been established that it has been established.
Scientists of Begurgey It was a perfect fit.
Saving some spot
Mendeleev’s expressions are called his table.
Fifty five elements have been discovered since the first scheme, according to their atomic mass. Of course, it’s not a problem.
Element 101 was named mendelevium to honor mendeleev’s contributions. This is actually even a rarer distinction of 50 scientists who have received a nobel prize in chemistry.
In 2016, four elements still had to be in the periodic table. With the addition of nihonium, moscovium, tennessine and oganesson, it is now complete.
Or is it?
It is up to you to get a little bit more information.
