Which of the lanthanide is the man made element

1.	Which of the lanthanide is the man made element
Answer» Uranium is a lanthanide and a man made element Explanation: The lanthanides are a collection of 15 chemical essentials, with atomic numbers 57 over 71. ALTOGETHER these elements have one valence electron in the 5d SHELL. The elements share features in mutual with the first element in the group -- lanthanum. The lanthanides are reactive, silver-colored metals. The man-made elements on the periodic table are those which are not found in nature, but have been synthesized in laboratories by SCIENTISTS. These elements are extraordinarily rare. Technetium was the first artificially produced element. It was isolated by Carlo Perrier and Emilio Segrè in 1937. Technetium was created by bombarding molybdenum atoms with deuterons that had been ACCELERATED by a device called a cyclotron.
