Nickel | The Canadian Encyclopedia

Nickel. Nickel is a naturally occurring element that exists in all soils and ranks 24th in the abundance of metals found in the earth's crust. It is a hard, tough, greyish-white metallic element and is thought to be an essential element for many plants and animals, and, many experts believe, for humans as well.
