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.
Potassium Fluoride is a good example for a typical alkali metal halide. The chemical formula for potassium fluoride is KF. In chemical synthesis and manufacture, the need for fluoride ion is satiated primarily by hydrogen fluoride; the second place always goes to potassium fluoride. Potassium fluoride can be refined from âCarobbiiteâ, a form which occurs very rarely in nature.
