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 metal.
Actinium is separated from uranium ores residues, after the extraction of uranium radium and polonium; are used classical methods in chemistry but the process is long and difficult.
yes,actinium is poisonos.
Actinium may be used in actinium-beryllium neutron sources or in radiotherapy.
Actinium is not soluble in water.
Batteries doesn't contain actinium.
Actinium is found in uranium and thorium ores.
Actinium is found in extremely low concentrations in residues from uranium ores (uraninite, pitchblende).
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 minute traces associated with uranium or thorium ores.
Actinium exist in all uranium minerals: ex. uraninite (pitchblende).
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.
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 radioactive metal; no taste !
