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 is a soft, malleable gray metal that was previously widely used in rat poisons and insecticides. Thallium itself and compounds containing the element are highly toxic. It is particularly dangerous because compounds containing thallium are colorless, odorless, and tasteless.hallium is a soft, malleable gray metal that was previously widely used in rat poisons and insecticides.
