Baron Axel Fredrik Cronstedt (/kroonstet/ 23 December 1722 – 19 August 1765) was a Swedish mineralogist and chemist who discovered the element nickel in 1751 [3] [4] [5] as a mining expert with the Bureau of Mines. [3]
Nickel is a chemical element; it has symbol Ni and atomic number 28. ... [33] 48 Ni, discovered in 1999, is the most proton-rich heavy element isotope known.
Perey discovered it as a decay product of 227 Ac. [177] Francium was the last element to be discovered in nature, rather than synthesized in the lab, although four of the "synthetic" elements that were discovered later (plutonium, neptunium, astatine, and promethium) were eventually found in trace amounts in nature as well. [178]

In 1751, a Swedish chemist and pupil of Stahl's named Axel Fredrik Cronstedt, identified an impurity in copper ore as a separate metallic element, which he named nickel. Cronstedt is one of the founders of modern mineralogy. [50] Cronstedt also discovered the mineral scheelite in 1751, which he named tungsten, meaning "heavy stone" in Swedish.
This concept [11] was the most important discovery in nucleosynthesis theory of the intermediate-mass elements since Hoyle's 1954 paper because it provided an overarching understanding of the abundant and chemically important elements between silicon (A = 28) and nickel (A = 60).

Named for the Americas, because it was discovered in the United States; by analogy with europium . The name of the continent America itself is derived from the name of the Italian navigator Amerigo Vespucci. Curium (Cm) 96 Curie, Marie and Pierre eponym Named in honour of Marie and Pierre Curie, who discovered radium and researched radioactivity.
