Gallium - Wikipedia

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 whiteIf too much force is applied, the gallium may fracture conchoidallyIt is in group 13 of the periodic table, and thus has similarities to the other metals of the group, aluminium, indium .
