4. Gallium
   Gallium: A rare metal with the atomic weight of 69. There are several isotopic forms of gallium that differ from it in atomic weight. One is gallium-68 which is produced by cyclotrons and emits gamma rays. The citrate form of gallium-68 is used as a radiotracer to locate sites of inflammation and tumor tissue within the body.

13. Gallium
    Gallium is a rare malleable metal element, discovered by spectrum analysis in 1875 by De Boisbaudran in the zinc-blende of Pierrefitte in the Pyrenees. It is of a greyish-white colour, has a brilliant lustre, and is fused by the mere warmth of the hand. In its properties it is related to aluminium.
