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).

Where was radon found?
Near Radium.
Is radium found alone in nature?

Can radium be found in nature as?
Radium exist only in very small concentrations in uranium and thorium ores; radium hasn't its own minerals.
What is found in the element radium?
Radium is an element; it has no sub-parts. Radium is a radioactive element, so it will slowly and spontaneously decay into other elements.
