Andre Louis Debierne discovered actinium in 1899. Friedrich Oskar Giesel independently discovered it in 1902 but Debierne is largely credited with the discovery.

The meaning of protactinium is before actinium. The name is from 1949, probably selected by IUPAC.
Francium was discovered by Marguerite Perey (from France) in 1939 during a study on actinium-227: she observed an energy level possibly attributable to a new element. After some chemical experiments she was sure that the radiation is from a new chemical element, after this called francium.
Batteries doesn't contain actinium.
Actinium is found in uranium and thorium ores.
Discoverers of actinium: Andre Louis Debierne - 1899 Fritz Giesel - 1902 Actinium is found in uranium minerals.
Actinium exist in minute traces in uranium and thorium ores.
Actinium exist in all uranium minerals: ex. uraninite (pitchblende).
Actinium exist in minute traces associated with uranium or thorium ores.
Actinium is found in very low concentrations in uranium ores, probably as an oxyde.
Actinium is separated from pitchblende. Actinium, AC, is found in uranium ore, a product of radioactive decay of uranium and ?æother unstable elements.
in 1899 in France.
Actinium is found in various countries around the world, primarily in mineral deposits such as uranium ores. It is a rare radioactive element and is typically extracted as a byproduct of uranium and thorium processing.
From Wikipedia "Actinium is found in trace amounts in uranium ore, but more commonly is made in milligram amounts by the neutron irradiation of 226Ra in a nuclear reactor. Actinium metal has been prepared by the reduction of actinium fluoride with lithium vapor at about 1100 to 1300°C."
Actinium does not form a common molecule like many nonmetals do; instead, it typically exists in metallic form or as part of compounds. As a member of the actinide series, actinium primarily occurs in the form of actinium(III) compounds, such as actinium oxide (Ac2O3). These compounds can form when actinium reacts with oxygen or other elements, but it does not have a stable, common molecular structure like diatomic or triatomic molecules found in other elements.
