Radium is an element, with atomic number 88. The element radium is a radioactive alkaline earth metal that is the decay product of thorium, element number 90. (Thorium is, itself, the radioactive daughter of uranium.) Radium (226Ra, the isotope that is the result of the alpha decay of thorium) has a half-life of 1602 years, and the element acts chemically like the other +2 elements in group 2 of the Periodic Table. It is highly radioactive and dangerous. (Links are provided to the Wikipedia article on radium and also to a related question.)
Today radium has only limited applications in research laboratories, for example for the preparation of radon standard solutions, in neutron sources of the type Ra-Be, etc.
Possible use in radiotherapy of some cancers.
Radium was used in the past for luminescent painting of watches and other instruments, was used in toothpaste, cosmetics, etc. These applications are not permitted now because radium is strongly radioactive and dangerous.
Well, atomic is something to do with atoms, and radium is an element of the periodic table. All elements are atoms, so basically, saying atomic radium is like saying atomic atom (since radium is an atom). I don't know where you heard that, but it will be much more simple to only say radium instead of atomic radium, because they mean the same thing.
Radium is a very rare metal and hasn't its own minerals; radium is a decay product of U and Th and exist in very low concentrations in uranium and thorium ores.
NAICS Code(s) 212291 (Uranium-Radium-Vanadium Ore Mining)
Separation and refining of radium and polonium from uranium ores by different chemical technology processes.
The principal problem is simply that so much ore is required to provide small amounts of radium. About one ton of pitchblende yields about one seventh of a gram of radium.
pitchblende was the first, but any good uranium ore will do as it is a daughter element of uranium's decay.
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.

Radium is an element itself. It was isolated by Marie Curie from Pitchblende, an ore of Uranium.

Radioactive yes, synthetic no. Radium is found in nature in very small trace amounts usually in uranium ore deposits.
The principal problem is simply that so much ore is required to provide small amounts of radium. About one ton of pitchblende yields about one seventh of a gram of radium.
Radium was discovered in France by the Curies, in samples of ore from the Austrian Empire, in 1898.
