Aktiniins
Aktiniins are a group of radioactive elements that are part of the actinide series in the periodic table. They are named after the first element in the series, actinium (At), which was discovered in 1899 by André-Louis Debierne. The aktiniins are characterized by their high atomic numbers, ranging from 89 (actinium) to 103 (lawrencium). These elements are typically produced in nuclear reactors or particle accelerators, as they are not found naturally in significant quantities on Earth.
The aktiniins exhibit a range of chemical and physical properties. They are all radioactive and have relatively
The study of aktiniins is of significant interest in nuclear chemistry and materials science. They are used
