The Full Story
Lise Meitner and Otto Hahn discovered protactinium in 1917 while studying the radioactive decay series of uranium. The element was rare and difficult to isolate, making its identification a significant achievement in early nuclear chemistry. Protactinium filled an important gap in the understanding of radioactive transformations. Later, it became known as one of the rarest naturally occurring elements on Earth.
