Radium was discovered in 1898 by Marie Curie, Pierre Curie and Gustave Bemont.
radium was not invented, it was discovered.
Radium was more or less discovered by accident while the Curies were looking for Uranium in samples of Pitchblende. In 1898, they discovered in tiny amounts, Polonium in July, and Radium in December.

Uranium, Polonium, Radium, Plutonium, etc
The term radio active came from the dangerous elements like Plutonium, Uranium, Radium and Caesium. These elements produces extreme heat and radioactivity. When exposed to these elements, one may get cancer problems. Pierre and Marie Curie discovered Radium but due to constant exposure to the element, they died of cancer. Plutonium and Uranium are used to produce atomic energy.
