Thallium: properties of free atoms. Thallium atoms have 81 electrons and the shell structure is 2.8.18.32.18.3. The ground state electron configuration of ground state gaseous neutral thallium is [ Xe ]. 4f 14. 5d 10. 6s 2. 6p 1 and the term symbol is 2 P 1/2.hallium atoms have 81 electrons and the shell structure is 2.8.18.32.18.3.
Research activity with thallium is ongoing to develop high-temperature superconducting materials for such applications as magnetic resonance imaging, storage of magnetic energy, magnetic propulsion, and electric power generation and transmission.03 Tl and 205 Tl are the only stable isotopes, and 204 Tl is the most stable radioisotope, with a half-life of 3.78 years. 202 Tl (half-life 12.23 days) can be made in a cyclotron, while 204 Tl is made by the neutron activation of stable thallium in a nuclear reactor.
