Its named that because radium means ray and it forms a ray when it's being "activated".
Maybe this answer here will help you....
When she realized that some uranium and/or thorium compounds had stronger radiation than uranium, she made the following hypothesis: there must be an unknown element in the compound which had a stronger radiation than uranium or thorium. Her work aroused the interest of her husband, Pierre Curie, who stopped his own research on crystals and joined the "detective work" with his wife. And Marie was proven right: in 1898 the Curies discovered two new radioactive elements: radium (named after the Latin word for ray) and polonium (named after Marie's home country, Poland).

Radium has not its own minerals; radium exist in extremely low concentrations in uranium and thorium ores.
Radium is typically separated from other materials found with it using chemical processes, such as solvent extraction or ion exchange chromatography. These methods exploit the chemical properties of radium to selectively separate it from other elements. Once separated, radium can be further purified through methods such as precipitation or distillation.
Yes, radium is found in nature as a trace element in uranium ores. It is typically found in combination with other elements in these ores, and it is not typically found in its pure, uncombined form in nature.
Radium is a radioactive element that is never found in its pure form in nature due to its highly reactive and unstable nature. It is typically found in minerals like uranium and thorium ores, and extracting pure radium requires complex and hazardous procedures.
nature
Radium exist in very small concentrations in some meteorites.
Radium is a decay product of uranium.
Fortunately radium don't exist normally in the human body; after an unhappy internal contamination radium can be fixed in bones.
Near Radium.
Radium exist only in very small concentrations in uranium minerals; radium hasn't its own minerals.
Radium exist only in very small concentrations in uranium and thorium ores; radium hasn't its own minerals.
Radium is an element; it has no sub-parts. Radium is a radioactive element, so it will slowly and spontaneously decay into other elements.
Radium exist in very low concentrations in uranium and thorium ores.
Radium exist in very low concentrations in uranium and thorium ores.
