Gadonnium is used for nuclear reactors, nuclear parts. It is also used for microwave parts the metal is used in some TV cables for. The metal is never used as itself it is used for making other items that need the metal.

The metal is a very soft metal, shiny and has a lot of detail in the rock. It belongs to the lanthanide group on the periodic chart. The metal is really magnetic at high room temperature. Gadonnium becomes very reactive below 1083k. Gadonnium reacts slowly In water and dissolves very fast in acid. The rock is found underneath a lot of other rare minerals. Gadonnium is a very rare earth element. It is really hard to find in the ground. Gadonnium salts are very toxic for your skin. If you come in contact with the salts you will get rashes on your skin and eyes they will appear everywhere on your body. Gadonnium has not been researched in very good detail.

He Gadonnuim ion cannot be used in its chloride, sulfate, or acetate forms because of poor tolerance and low solubility in water in the neutral pH range. Although toxic by itself.
