    Cesium
In summary, cesium and thallium have various uses, including in nuclear medicine and infrared optical materials. Thallium can also be used to produce low melting glasses and glasses with a high index of refraction. However, it is also poisonous and has been used in crimes. It is not recommended to buy cesium or thallium at a chemist's store.

Here are two:

Radioisotopes of both elements are used in nuclear medicine for the diagnosis of various medical conditions.

Cs-137 is also used as a source for radiotherapy machines, to kill cancer cells.

Here is another for thallium..


Thallium bromide-iodide crystals have been used as infrared optical materials.


Thallium along with sulfur or selenium and arsenic is used to produce low melting glasses witch become fluid between 125 and 150C. These glasses have properties at room temperatures similar to ordinary glasses and are said to be durable and insoluble in water.

Thallium oxide has been used to produce glasses with a high index of refraction

But thallium is poisonous as well isn't it? I once saw a crime programme on Discovery Channel where a murderer had used thallium to kill a man.

Can I buy cesium or thallium at a chemist's store?

Cannot answer that.
 

1. What are Cesium and Thallium?

Cesium and Thallium are two elements on the periodic table. They are both metals that are part of the alkali metal group.

2. What are some common uses of Cesium and Thallium?

Cesium is commonly used in atomic clocks, as well as in photoelectric cells and vacuum tubes. Thallium is used in infrared detectors, photocells, and as a doping agent in semiconductors.

3. Are Cesium and Thallium toxic?

Cesium and Thallium can be toxic in certain forms and concentrations. Cesium compounds can cause irritation to the eyes and skin, while Thallium compounds can be poisonous if ingested.

4. How do Cesium and Thallium react with other elements?

Cesium is highly reactive and can react violently with water, while Thallium is less reactive but can still react with acids and water. Both elements can also form various compounds with other elements.

5. Can Cesium and Thallium be found in nature?

Cesium and Thallium can be found in nature, although they are relatively rare. Cesium is typically found in minerals like pollucite and lepidolite, while Thallium is often found in ores of other metals such as zinc and lead.
