Radium is a radioactive element in Group 2 (IIA) and Row 7 of the periodic table.

The periodic table is a chart that shows how chemical elements are related to each other.

Both polonium and radium were more radioactive than uranium.

For their work on radioactivity, the Curies were awarded the 1903 Nobel Prize in physics.

Radium was discovered in 1898 by Marie Curie (1867-1934) and her husband, Pierre Curie (1867-1934).

It was found in an ore of uranium called pitchblende.

In 1896, Becquerel made a discovery about the ore called pitchblende. Becquerel found that pitchblende gives off radiation that acts much like light.

The main difference is that the radiation from pitchblende is not visible to the human eye.

We will continue to talk about these in the following pages.Becquerel's discovery caused great excitement among scientists.
