nervous system definition. The system in the body that controls internal functions of the body and receives, interprets, and responds to stimuli. The nervous system is made up of the brain, the spinal cord, the nerves, and the sense organs, such as the eye and ear.
Caesium fluoride or cesium fluoride is an inorganic compound usually encountered as a hygroscopic white solid. It is used in organic synthesis as a source of the fluoride anion.Caesium has the lowest electronegativity of all non-radioactive elements and fluorine has the highest electronegativity of all elements.aesium fluoride can be prepared by the reaction of caesium hydroxide (CsOH) with hydrofluoric acid (HF). The resulting salt can then be purified by recrystallization.
Cesium compounds are used in specialized alkaline batteries that are designed to work in subzero climates. Cesium carbonate is used in the production of special glass and glass products. The most accurate clock in the world, the âatomic clock,â measures time based on the very precise vibration of the electrons in the outer shell of the cesium atom.
