Thallium - Wikipedia

Thallium is a chemical element with the symbol Tl and atomic number 81. It is a gray post-transition metal that is not found free in nature. When isolated, thallium resembles tin, but discolors when exposed to air. Chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production.

TIME COURSE: Adverse health effects from thallium are dose dependent, and occur in three stages.The gastrointestinal phase may occur immediately with large ingestions or may be delayed 24 to 48 hours with smaller ingestions. This is followed by a neurological phase 2 to 5 days or more after ingestion, although it may occur as early as 12 hours after massive ingestion.

Thulium is a chemical element with the symbol Tm and atomic number 69. It is the thirteenth and third-last element in the lanthanide series. Like the other lanthanides, the most common oxidation state is +3, seen in its oxide, halides and other compounds; because it occurs so late in the series, however, the +2 oxidation state is also stabilized by the nearly full 4f shell that results.
