31 Ga 69.723 Gallium
GALLIUM!
  • By Alexis Paxton
  • Mr. Manning

Poperties and Uses Of Gallium
  • Melting Point 29.78 C (302.93 K, 85.604004 F)
  • Boiling Point 2403.0 C (2676.15 K, 4357.4 F)
  • Number of Protons/Electrons 31
  • Number of Neutrons 39
  • Density _at_ 293 K 5.907 g/cm3
  • Color White/Silver
  • Gallium wets glass or porcelain, and forms a
    brilliant mirror when it is painted on glass
  • Used for doping semiconductors and producing
    solid-state devices such as transistors
  • Gallium arsenide converts electricity into
    coherent light
  • Alloying
  • 90 tons of gallium (2 or 3 years of world
    production) is used to detect solar neutrinos by
    the use of the reaction nu 71Ga gt 71Ge e-.
    The rate, although very low (less than 1
    interaction per day in 30 tonnes of Ga) makes
    gallium unique for this purpose. Two experiments
    are running - GALLEX using 30 tons in the Gran
    Sasso underground laboratory (Italy) and SAGE
    with 60 tons in the Baksan laboratory in Caucasus
    (Russia). thanks Michel

Facts about GALLUIM!!
  • Date of Discovery 1875
  • Discoverer Paul Emile Lecoq de Boisbaudran
  • Name Origin From the Latin word Gallia, the old
    name of France
  • Uses semiconductor production
  • Obtained From bauxite, germanite, coal

Gallium poem!
  • Gallium was discpvered in 1875
  • By Paul Emily Lecoq De Boisbaudran.
  • Gallium has alloying that it contains.
  • Its symbol is GA
  • And is used to wet glass and is brillant mirror
    when painted on glass!!
