Radium exist in very small concentrations in uranium ores. It was first discovered in uranium minerals from Joachimsthal, North Bohemia (now Jachymov in the Czech Republic) by Marie Curie, Pierre Curie and Gustave Bemont (1898).
Radium is in the alkaline earth metals.
Radium is a highly radioactive alkali earth metal, and it can be found in trace amounts in some water sources and in some soil or rock samples. That means this stuff isn't found in the atmosphere. (It may be in some dust, but not likely.) But it will be found in some places in the lithosphere (the ground or the earth) or the hydrosphere (the water). Radium is associated with the radioactive decay of uranium, so where traces or deposits of uranium ore are found, this stuff will be around. A link to the Wikipedia article on radium is provided.
The abundance of radium in the earth crust is 9.10-10 mg/kg.
Radium is a solid alkaline earth metal at room temperature.
Radium is a natural chemical element, solid, alkaline earth metal.
Radium is usually found in compounds. Since it is an alkaline earth metal it is to reactive to exist in its elemental states in most environments, and especially in Earth's oxidizing atmosphere.
