Explanation:
The american scientist Glenn Seaborg has many important contribution the chemistry. His work made a significant change in the mendeleev's periodic table. He introduced new row that is placed below the lanthanides row, called actinides.
He was co-discoverer or principle discoverer of plutonium and einsteinium. He was responsible for the discovery of more than 100 medical isotopes.
