Collective Work of Chemists
From an article on LinkedIn:
Twelve elements were known from the Ancient Times, and were described by Romans and Greeks. The remaining 106 elements have been discovered by scientists of 15 different countries during the last 4 centuries. In addition, 19 elements of those 106 (18%) have been co-discovered by researchers of two countries.
Although some of them (like Bromine or Thallium) were isolated separately at the same time by chemists of different nationalities within the race to discover new elements in 18th-21st centuries, most of them have been obtained since then through collaborative research, like the recently discovered Ununpentium, Ununseptium and Ununoctium.
Another example is the isolation of Radium and Polonium by the Polish Maria Skłodowska-Curie and her French husband, Pierre Curie.
Thus, Periodic Table is the result of a collective and long-term work of hundreds of scientists.
It is noteworthy to see that Russia and United States have discovered mainly artificial elements.
