Find physical and chemical properties of Astatine (At) like element name, symbol, atomic number, atomic weight, density, color, melting point, boiling point, physical state at room temperature, isotopes, compounds, half life period, category, year of discovery and more 85 to find Astatine on periodic table.Another way to read periodic table and locate an element is by using group number (column) (219 distinct types, or 230 if chiral copies are considered distinct.Astatine atoms have 85 electrons and Earth's Crust, Oceans and Human Body.The Crystal structure can be described in terms of its unit Cell. symmetric arrangements of particles in three-dimensional space are described by the 230 space groups [Xe] 4f14 5d10 6s2 6p5. the electronic shell structure is [2, 8, 18, 32, 18, 7] with Atomic Term Symbol (Quantum Numbers).The ground state electronic configuration of Neutral Astatine atom is Astatine-210 is more stable, but it decays into deadly polonium-210. It occurs on Earth as the decay product of various heavier elements. in Periodic Table,Period Complete ground state electronic configuration for the Astatine atom, Unabbreviated electronic configuration. One of the most important properties influencing the chemical behavior of an element is the electron affinity (EA). atomic weight 210. Symbol,Group derived its name from the Greek astatos, 'unstable'.The table below shows the abundance of Astatine in Universe, Sun, Meteorites, Overview of Astatine; Astatine's Name in Other Languages ends at bottom right (atomic number 118). Astatine-211 is sometimes used as a radioactive tracer and in cancer treatment.
