Thallium, then, like its congeners, is a soft, highly electrically conducting metal with a low melting point, of 304 °C. [ 11 ] A number of standard electrode potentials, depending on the reaction under study, [ 12 ] are reported for thallium, reflecting the greatly decreased stability of the +3 oxidation state: [ 11 ]
The thallium was slipped into bottles of Coca-Cola at the Carr and Trepal homes. [27] Thallium was the poison of choice for Saddam Hussein to use on dissidents, which even allowed for them to emigrate before dying. [28] In 1995, Zhu Ling was the victim of an unsolved attempted thallium poisoning in Beijing, China.
Since thallium(I) sulfate is a simple powder with indistinctive properties, it can easily be mistaken for more innocuous chemicals. It can enter the body by ingestion, inhalation, or through contact with the skin. The thallium(I) cation is very similar to potassium and sodium cations, which are essential for life.
Thallium(I) iodide has the CsCl crystal structure. The monohalides, also known as thallous halides, all contain thallium with oxidation state +1. Parallels can be drawn between the thallium(I) halides and their corresponding silver salts; for example, thallium(I) chloride and bromide are light-sensitive, and thallium(I) fluoride is more soluble in water than the chloride and bromide.
Thallous acetate or thallium(I) acetate is a salt of thallium and acetate with the chemical formula TlCH 3 COO. It is used in microbiology as a selective growth medium . [ 3 ] It is poisonous.
The mucus can also turn black when environmental irritants, like dust particles, smoke or other air pollutants, get stuck in the nasal passages. Serious fungal infections can darken mucus as well ...

Example thallide monoclinic Cs 7.29 K 5.71 Tl 13 containing [Tl 6] 6− and [Tl 7] 7− clusters. Thallides are compounds containing anions composed of thallium.There are several thallium atoms in a cluster, and it does not occur as a single Tl − in thallides.
