Element is on Nickel
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrousmetal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel shows a significant chemical activity that can be observed when nickel is powdered to maximize the exposed surface area on which reactions can occur, but larger pieces of the metal are slow to react with air at ambient conditions due to the formation of a protective oxide surface.

facts (must have 3) Nickel is present in metallic meteorites and so has been in use since ancient times.
Artifacts made from metallic meteorites have been found dating from as early as 5000 BC – for example beads in graves in Egypt.(1)
Iron is the most abundant element in metallic meteorites, followed by nickel.
