F Fluorine – Element Information, Facts, Properties, Trends,Uses, Comparison with other elements

Fluorine History

The element Fluorine was discovered by André-Marie Ampère in year 1886 in France . Fluorine derived its name from the Latin fluere, meaning 'to flow'

Fluorine Presence: Abundance in Nature and Around Us

The table below shows the abundance of Fluorine in Universe, Sun, Meteorites, Earth's Crust, Oceans and Human Body.

Crystal Structure of Fluorine

The solid state structure of Fluorine is Base Centered Monoclinic.

The Crystal structure can be described in terms of its unit Cell. The unit Cells repeats itself in three dimensional space to form the structure.

Unit Cell Parameters

The unit cell is represented in terms of its lattice parameters, which are the lengths of the cell edges Lattice Constants (a, b and c)

and the angles between them Lattice Angles (alpha, beta and gamma).

The positions of the atoms inside the unit cell are described by the set of atomic positions ( x_i, y_i, z_i) measured from a reference lattice point.

The symmetry properties of the crystal are described by the concept of space groups. All possible symmetric arrangements of particles in three-dimensional space are described by the 230 space groups (219 distinct types, or 230 if chiral copies are considered distinct.

Space Group Name	C12/c1
Space Group Number	15

Ground State Electronic Configuration of Fluorine - neutral Fluorine atom

The ground state electronic configuration of Neutral Fluorine atom is [He] 2s2 2p5. The portion of Fluorine configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [He]. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used.This is important as it is the Valence electrons 2s2 2p5, electrons in the outermost shell that determine the chemical properties of the element.
