Gadolinium is very stable in nature. It does not form ionic compounds in nature because it is used for MRI’s. It combines with oxygen to help see a contrast on the MRI film.

Californium has an isotope Cf-249 which is from the beta decay of Bk-249. Other isotopes are produces by irradiation of reactions, such as Cf-250,Cf-251, and Cf-252 have been isolated.

My element, Platinum, doesnt usually form ionic compounds in nature because if it is mixed with oxygen or hydrogen, it explodes.

My element, Francium, dosen’t normally form any Ionic compounds in nature. However, it does make one of the strongest Ionic compounds made when with  fluoride; it molecular formula is FrFl.

One of the most common ionic compounds that my element chlorine forms in nature is Sodium Chloride, or table salt. Chlorine forms a bond with Sodium to form a crystalline solid called NaCl. The positively charged Na ions, and negatively charged Cl ions are held together by an electrostatic force the creates an ionic bond. Another ionic compound formed would be Sodium Hypochlorite or bleach. This compound consists of three elements: Na, Cl, and O.  Sodium Hypochlorite can be used in household cleaning products as well as for water treatment in pools. Hypochlorous Acid or HOCL, is also used as a disinfectant, a bleach, and an oxidizer. This compound is formed when Chlorine is mixed with water.

Lithium forms many ionic compounds in nature. Lithium forms nitride by reaction with N2, the formation of an oxide when burnt in O2, salts with similar solubilities, and thermal instability of the carbonates and nitrides.

The compounds of cobalt found in nature is Cobalt (II) Flouride, Cobalt (II) Chloride, Cobalt (II) Bromide and Cobalt (II) Iodide. These are normally found in Halogens.

The reduction potential for the reaction:

Co3+ + e → Co2+

Platinum is easily worth 1 million dollars! Platinum is a hypoallergenic virtually pure precious metal and is 3o times rarer than gold. platinum in jewerly is a bright, shiny substance that if you just look at it, it looks like its worth million dollars. and if your seen wearing it you know someone’s gonna think ” oooh platinum, you must be a millionaire!” and in music, the highest you can go is platinum.
