Actinium is a soft, silvery-white metallic element that is radioactive. It was discovered by French chemist Andre-Louis Debierne in 1899.
In the periodic table, actinium belongs to the group of transition metals. The actinide series is made up of fifteen similar elements. These include actinium, lanthanum, and lawrencium. Despite its low atomic mass, actinium has a number of applications in the medical field, particularly in radio-immunotherapy.
Actinium is not only used to produce neutrons, it also has a significant role in cancer treatment. It is used to target radiation therapy on specific tumors.
Actinium is a member of the actinide series and has similar chemical properties to the rare earth element lanthanum. It is considered a relatively scarce element. However, it has a high radioactivity, which could negatively affect future generations.
Actinium is a rare metal that is very radioactive. It has been found to be 150 times more active than radium. This factor makes it attractive to future radioisotope thermoelectric generators.
Actinium has a very high thermal conductivity of 12 W/(m*K). Because of its radioactivity, it can cause damage to cells. For this reason, it is highly recommended that it be handled by experts.
Actinium’s atomic number is 89. The number of protons and electrons in an atom is the same, but the number of neutrons varies. Depending on the isotope, the number of neutrons can range from 138 to 135 (natural).
Neutrons are a permanent part of an atom. They are drawn to the nucleus, which is the center of the atom. Other particles within an atom include the proton and the neutrino.
