What is thallium made of?
Thallium is found in several ores. One of these is pyrites, which is used to produce sulfuric acid. Some thallium is obtained from pyrites, but it is mainly obtained as a by-product of copper, zinc and lead refining. Thallium is also present in manganese nodules found on the ocean floor.
What is the chemical structure of thallium?
thallium (Tl), chemical element, metal of main Group 13 (IIIa, or boron group) of the periodic table, poisonous and of limited commercial value. Like lead, thallium is a soft, low-melting element of low tensile strength….thallium.

Why is thallium used for?
Thallium is used mostly in manufacturing electronic devices, switches, and closures, primarily for the semiconductor industry. It also has limited use in the manufacture of special glass and for certain medical procedures.
How does thallium affect the human body?
Thallium can affect your nervous system, lung, heart, liver, and kidney if large amounts are eaten or drunk for short periods of time. Temporary hair loss, vomiting, and diarrhea can also occur and death may result after exposure to large amounts of thallium for short periods.
Does thallium dissolve in water?
Water: Thallium cannot be used to contaminate water because it does not dissolve in water.
What element is most similar to thallium?
Thus, very few electrons are available for metallic bonding, similar to the neighboring elements mercury and lead, and hence thallium, like its congeners, is a soft, highly electrically conducting metal with a low melting point of 304 °C.
How much thallium is toxic to humans?
Thallium poisoning is via ingestion or absorption through the skin. The lethal dose for humans is 15-20 mg/kg, although much small doses have also led to death.
How is thallium used in everyday life?
Everyday uses. But thallium is also a chemical which features in our everyday lives. Its derivatives are used in many objects, from medical scans, electronic components and optical lenses to imitation jewellery, low temperature thermometers, and green-coloured fireworks.
What are the common uses of thallium?
the sulphate was widely used as a rodenticide and ant killer.
What are the properties of thallium?
Thallium melts easily.
What is the cure for thallium poisoning?
The current therapy for thallium poisoning is the use of prussian blue and potassium chloride. Potassium therapy is probably the single most effective agent in the treatment of thallium poisoning.
