Gallium is a chemical element; it has symbol Ga and atomic number 31. Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875,[7] gallium is in group 13 of the periodic table and is similar to the other metals of the group (aluminium, indium, and thallium). Element...

As such, it was the first of Mendeleev's elements to be uncovered and it was this discovery that paved the way for the general acceptance of the periodic table.20 Gallium is dominated by the + III oxidation state and some of these compounds are very promising candidates for anticancer ...
The discovery of gallium filled a spot predicted by Mendeleev's periodic table. Gallium took the place of the placeholder element eka-aluminum. Gallium was first identifiedusing spectroscopyby its distinct pair of violet spectral lines. Gallium's melting point (302.93 K) is low enough to melt th...
Discovery of Gallium Before the discovery of gallium its existence and main properties were predicted by Russian chemist Dmitri Mendeleev. He named the hypothetical element eka-aluminum as he predicted the element would sit below aluminum on the periodic table. ...
other minerals. It is used in semiconductor technology, as a component of various low-melting alloys, and in producing blue light-emitting diodes. Atomic number 31; atomic weight 69.72; melting point 29.78°C; boiling point 2,403°C; specific gravity 5.907; valence 2, 3. SeePeriodic Table....
Must discovery be attributed to those who only detected the elements, or to those who isolated the oxides of the elements, or to those who isolated the free elements themselves? Arguments can be made for recognizing all of these cases.

The 1869 publication of Dmitri Mendeleev's systematic table contained lacunae left by the author to signal the presumed existence of not-yet-discovered simple bodies. Three of the missing elements were discovered within a span of time from 1875 to 1886: gallium, scandium, and germanium. Aside fr...
