Nickel is a naturally occurring metallic element with a silvery-white, shiny appearance. It is the fifth most common element on earth and occurs extensively in the earth’s crust and core. Nickel, along with iron, is also a common element in meteorites and can even be found in small quantities in plants, animals, and seawater.
While the concentration of nickel in the earth’s crust is 80 parts per million, the earth’s core consists mainly of a nickel-iron alloy.
