History

• 1871 Dmitrii Ivanovich Mendelev predicts the
  existance and properties of the element after
  zinc in the periodic table . He gives it the name
  'eka aluminium'.
• 1875 Paul Emile Lecoq de Boisbaudran discovers
  gallium. Its properties closely match those
  predicted by Mendelev in 1871 Its properties
  closely match those predicted by Mendelev in
  1871.
