How did Edwin McMillan discover the element neptunium?
While studying nuclear fission, McMillan discovered neptunium, a decay product of uranium-239. In 1940, in collaboration with Philip H. Abelson, he isolated the new element and obtained final proof of his discovery.
What element is synthesized by EM Macmillan in 1940?
element 93
Every element past uranium in the periodic table has been made by scientists in high energy particle accelerators. The first transuranium element made was element 93, discovered by E. M. Macmillan and P. H. Abelam at the University of California at Berkeley in 1940.

What was neptunium the first of?
Abelson first found neptunium in 1940 after uranium had been bombarded by neutrons from the cyclotron at Berkeley, California. The element was named after the planet Neptune, which is the first planet beyond Uranus….neptunium.

Who discovered uranium 237?
Missing element 93 was discovered by E.M. McMillan and P.H. Abelson11) of the California University group in 1940, and named neptunium (Np). In 1942, 237Np was synthesized in larger amounts, and its half-life was revealed to be 3 × 106 y (2.144 × 106 y, at present) by A.C. Wahl and G.T.
What is the 93 element?
Between those planets sits Neptune, and the gap between the two elements leaves a space for their relatively unsung cousin, neptunium – element number 93 in the periodic table.
