is composed of diatomic molecule F2. Fluorine was discovered in 1886 by Joseph Henri Moissan‚ who also produced the first artificial diamond. The element Fluorine has nine protons and electrons and ten neutrons. Fluorines atomic mass is 188.998404 amu. Fluorines atomic number is 9. Fluorines density at 293 K is 1.696 g/cm. That makes fluorine about 1.3 times as dense as air. The electron configuration of Fluorine is [He] 2s2 2p5. Its crystal structure is cubic. To continue Fluorines name origin came

Core Module 1: The Chemical Earth Contextual Outline The Earth includes a clearly identifiable biosphere‚ lithosphere‚ hydrosphere and atmosphere. All of these are mixtures of thousands of substances and the use of this pool of resources requires the separation of useful substances. The processes of separation will be determined by the physical and chemical properties of the substances. In order to use the Earth’s resources effectively and efficiently‚ it is necessary to understand the properties
