CAS 7440-46-2
:Cesium
Description:
Cesium, with the CAS number 7440-46-2, is an alkali metal characterized by its soft, silvery-gold appearance and high reactivity. It is one of the most electropositive and alkaline elements, readily losing its outermost electron to form positive ions. Cesium has a low melting point, allowing it to be liquid at slightly above room temperature, and it is highly reactive, particularly with water, producing cesium hydroxide and hydrogen gas. This reactivity necessitates careful handling, as it can ignite spontaneously in air. Cesium is primarily used in atomic clocks, which are known for their precision, and in various applications in the fields of electronics and optics. Additionally, cesium isotopes have applications in medical imaging and radiation therapy. Due to its high atomic mass and unique properties, cesium plays a significant role in scientific research and technological advancements. However, its reactivity and the potential for forming hazardous compounds require strict safety protocols during its use and storage.
