Others are a bit scarier, like thallium and thorium that are deadly poisons, and tellurium, which makes you smell of rotten onions for weeks. Basically what they've done is list everything that occurs in even trace amounts in mixed monazite sand, which is kind of what the stuff inside looks like.

Thallium, a soft, bluish-gray, malleable heavy metal, was discovered by Sir William Crookes in 1861 while he was making spectroscopic determinations for tellurium on residues from a sulfuric acid plant. Although the metal is reasonably abundant in the Earth's crust at a concentration estimated to be about 0.7 part per million, it exists mostly in association with potassium

Thallium is an element having the chemical symbol Tl and is a soft, mal leable, heavy metal with a silver-white luster (Lee, 1971). Industrial uses of thallium include the manufacture of alloys, electronic devices, and spe cial glass. Many thallium-containing catalysts have been patented for in dustrial organic reactions (Zitko, 1975).",.

Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90. Thorium is silvery and tarnishes black when it is exposed to air, forming thorium dioxide; it is moderately soft, malleable, and has a high melting point.Thorium is an electropositive actinide whose chemistry is dominated by the +4 oxidation state; it is quite reactive and can ignite in air when ...
He extracted thallium sesquichloride and isolated the metal new by electrolysis. Only after his discovery, he found out that Crookes had earlier discovered and named the new element, and gave Crookes the honour. Crookes presumed that his Thallium was something of the order of Sulphur, Selenium or Tellurium but Lamy found it to be a metal.
Gold, thallium, indium and tellurium are separated and concentrated from the sample digest by a two-step MIBK extraction at two concentrations of hydrobromic add. Gold and thallium are first extracted from 0.1M hydrobromic acid medium, then indium and tellurium are extracted from 3M hydrobromic acid in the presence of ascorbic acid to eliminate ...
Tellurium Properties. Tellurium is a Block P, Group 16, Period 5 element. The number of electrons in each of Tellurium's shells is 2, 8, 18, 18, 6 and its electron configuration is [Kr] 4d 10 5s 2 5p 4.In its elemental form tellurium's CAS number is 1.
Thorium reacts with hydrogen to form the thorium hydrides ThH 2 and Th 4 H 15, the latter of which is superconducting below the transition temperature of 7.5–8 K; at standard temperature and pressure, it conducts electricity like a metal. Thorium is the only element that forms a hydride higher than MH 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. Because of this high toxicity, the World Health Organization ...
