Polonium: A Brief History and Discovery

Polonium is a radioactive, highly toxic element with an atomic number of 84 and a symbol Po. It was first discovered in 1898 by Marie Curie and her husband Pierre Curie, who were conducting research into the discovery of new radioactive elements. In this article, we will explore the history and discovery of polonium, including its naming and symbol.

Discovery of Polonium

Polonium was discovered by Marie and Pierre Curie in 1898 as part of their research into the study of radiation and the discovery of new chemical elements. They used a pitchblende ore sample found in Jchymov, now in the Czech Republic, and obtained this rare element via lead chromatography and fractionation-based on polonium’s high radioactivity.

Marie and Pierre Curie identified the extremely radioactive substance responsible for the luminescent emissions as a new element, which they named polonium, to honor Marie’s country of birth, Poland. At first, the Curies believed they had discovered a new element related to lead, but it became clear that they had stumbled across a new element altogether when they extracted what was then called Polonium X.

Further analysis revealed that the cellular matter contained two other radioactive substances which the Curies would later name Radium and Actinium.

Naming and Symbol of Polonium

The Curies named polonium after Marie Curie’s native country, Poland. At the time, Poland was partitioned amongst three powers Russia, Prussia, and Austria, and her homeland had lost its political independence.

The naming was an act of defiance, and also a tribute to the country where she was born. Marie chose the name Polonium as a homage to her country, and the Latin name for Poland is Polonia.

She hoped that the discovery of this new radioactive substance would be a source of pride for all Poles, and that it would help her country assert its independence. The symbol “Po” was given to polonium by the International Union of Pure and Applied Chemistry (IUPAC) in 1957.

At the time of its discovery, Polonium did not have a symbol, but as new elements were discovered, they were assigned symbols based on the first two letters of their name. Given the importance of Marie Curie’s discovery, the symbol Po was later assigned to polonium to commemorate this historical event and its significance in science.


Polonium’s discovery is integral to the study of radiation and nuclear chemistry. It was a significant step in the development of nuclear energy and radiation-based treatments.

The discovery of polonium is also significant in Polish history, as it represents the determination of a nation to strive for scientific excellence even when facing political adversity. In conclusion, the discovery of polonium by Marie and Pierre Curie is an important milestone in the history of science.

The naming of polonium as a tribute to Marie Curie’s country of origin, Poland, highlights the resilience of the Polish people in the face of political suppression. Today, polonium’s use is highly regulated due to its highly toxic nature, but its discovery has led to significant discoveries related to nuclear chemistry and medicine.
