Name: nuclear number 28         Symbol: Ni         Atomic number: 28         Atomic cant everyplace: 58.6934 (2) Minerals containing atomic number 28 note were of value for colouring glass green. The mineral white plague for colouring glass was called kupfer nickel (false copper). Nickel was discovered by powerfulness Axel Frederik Cronstedt in 1751 in a mineral called niccolite. Apparently, he had tag to extract copper from this mineral hardly got n wiz at all, obtaining instead a white metal that he called nickel after the mineral from which it was extracted. detect by: Axel Fredrik Cronstedt Discovered at: Sweden Discovered when: 1751         Origin of name: From the German boy kupfernickel meaning Devils copper or St Nicholass (OLd Nicks) copper Fluorides         NiF2: nickel (II) fluoride Chlorides         NiCl2.6H2O: nickel (II) chloride 6-water         NiCl2: nickel (II) chloride Bromides         NiBr2: nickel (II) bromide Iodides         NiI2: nickel (II) iodide Oxides         NiO: nickel (II) oxide         Ni2O3: nickel (III) oxide Sulfides         NiS: nickel (II) sulphide         NiS2: nickel disulphide         Ni3S2: nickel sulphide Selenides         NiSe: nickel (II) selenide         Ground state negatron configuration: [Ar].3d8.4s2         Shell twist: 2.8.16.
