Name:Cesium
Article Data:128
Molecular Structure:
Formula:Cs
Molecular Weight:132.905
Synonyms:Cesium-133
EINECS:231-155-4
Density:1.873 g/mL at 25 °C(lit.)
Melting Point:28.5 °C(lit.)
Boiling Point:705 °C(lit.)
Flash Point:
Solubility:reacts

Stability

Flammable solid; highly flammable in powder form. Moisture-sensitive. Incompatible withchlorine, phosphorus, water.

Toxicology

Harmful if swallowed or inhaled and in contact with skin.

Appearance:silvery, light ductile metal

Hazard Symbols:Dangerous fire and explosion risk, ignites spontaneously in moist air, may explode in contact with sulfur or phosphorus, reacts violently with oxidizing materials, causes burns in contact with skin.

Risk CodesR14/15;R34;

Safety: Moderately toxic by intraperitoneal route. Cesium is quite similar to potassium in its elemental state. It has been shown, however, to have pronounced physiological action in experimentation with animals. Hyper-irritability, including marked spasms, has been shown to follow the administration of cesium in amounts equal to the potassium content of the diet. It has been found that replacing the potassium in the diet of rats with cesium caused death after 10–17 days. Ignites spontaneously in air. Violent reaction with water, moisture, or steam releases hydrogen gas which explodes. Violent reaction with acids, halogens, and other oxidizing materials. Incandescent reaction with nonmetals (e.g., sulfur, phosphorus). See also SODIUM.
