Gallium - Wikipedia

Gallium is a chemical element with the symbol Ga and atomic number 31. Elemental gallium is a soft, silvery blue metal at standard temperature and pressure; however in its liquid state it becomes silvery white.If too much force is applied, the gallium may fracture conchoidally.It is in group 13 of the periodic table, and thus has similarities to the other metals of the group, aluminium, indium ...

Gallane - Wikipedia

Reduction of gallane gives gallium metal. Upon treatment with a standard acid, it converts to a gallium(3+) salt and hydrogen gas. Oxidation of gallane gives Ga(OH) 3, gallium(III) hydroxide. Unsolvated gallane is in chemical equilibrium with digallane(6), being the dominant species with increasing temperature.
