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).
As for the element radium, the name is derived from the Latin word radius=radiation. The suffix on is the same as for the others noble gases (excepting helium).
Radium was called radium because this element is strongly radioactive (radius in the Latin language is radiation).
nature
Radium is only found in trace amounts in uranium ore. It is not a stable element, so it cannot be found by itself like other elements (say, oxygen) can.
she made a new element. the element was radium. radium is used in matirials such as lipstick!!!!!!!! She found the isolation of poloniam and radium and used radium for x-rays which helped in a war.
Equiptinite/ quartzite
Radium was discovered by the Curies in France in 1898, in samples of pitchblende which were found to be radioactive after removal of the uranium.
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 and thorium ores; radium hasn't its own minerals.
Radium exist only in very small concentrations in uranium minerals; 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.
