Andre Louis Debierne discovered actinium in 1899. Friedrich Oskar Giesel independently discovered it in 1902 but Debierne is largely credited with the discovery.
Actinium is a natural element but because is extremely difficult to be separated from ores it is practically obtained artificially in laboratory.
Actinium is a solid at room temperature.
No, actinium is not a metalloid. It is a radioactive metal element that belongs to the actinide series on the periodic table.
Actinium is not very soluble in water. Its solubility is extremely low, with only a small fraction of actinium ions forming in a dissolved state in water.
Actinium can be separated from other materials through a process called solvent extraction. This involves using specific organic solvents that selectively extract actinium from the mixture based on its chemical properties, allowing for its isolation and purification. Another method is ion exchange chromatography, where actinium is separated based on its affinity for certain resins or columns.
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 is a trivalent metal; only in the actinium hydride is divalent.
