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.
Thallium: isotope data. Thallium has two stable isotopes and one of these, Tl-203, is used to produce one of the (workhorses (of nuclear medicine: Tl-201.Tl-201 is used extensively for imaging and in particular for perfusion tests of the myocardium.hese tests are done to determine the damage to the heart from a heart attack or from heart diseases. Tl205 has been proposed as an alternative target for the production of Tl-201. Tl-205 is also used in nuclear magnetic resonance research.
