Yes Radium is found in nature.
"(L. radius: ray) Radium was discovered in 1898 by Mme. Curie in the pitchblende or uraninite of North Bohemia, where it occurs. There is about 1 g of radium in 7 tons of pitchblende. The element was isolated in 1911 by Mme. Curie and Debierne by the electrolysis of a solution of pure radium chloride employing a mercury cathode; on distillation in an atmosphere of hydrogen, this amalgam yielded the pure metal.
"Originally, radium was obtained from the rich pitchblende ore found in Joachimsthal, Bohemia. The carnotite sands of Colorado furnish some radium, but richer ores are found in the Republic of Zaire and the Great Lake region of Canada. Radium is present in all uranium minerals, and could be extracted, if desired, from the extensive wastes of uranium processing. Large uranium deposits are located in Ontario, New Mexico, Utah, Australia, and elsewhere.
Radium is a natural chemical element, solid, alkaline earth metal.
Radium is a natural chemical element, an alkali earth metal; but some isotopes of radium can be obtained artificially.
Radium is a natural chemical element, discovered in 1898, radioactive, alkaline earths group, metal, solid, rare in the nature.
Radium is a chemical element, not a compound.
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 is a chemical element, not a mixture.
Radium has 138 neutrons.
Radium is an element itself. It was isolated by Marie Curie from Pitchblende, an ore of Uranium.
Polonium is a rare radioactive element with symbol Po and atomic number 84. It was discovered by Marie Curie and her husband Pierre Curie in 1898. Radium is another radioactive element with symbol Ra and atomic number 88. It is also discovered by Marie Curie, and both polonium and radium are highly toxic and carcinogenic.
Deuterium is a natural isotope of hydrogen with one neutron and one proton.
Radium is an element, atomic number 88.
Radium is not used to produce energy.
