Homonym: nickel (Coin)
Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white metal that is hard and ductile, meaning it can be shaped without breaking. Nickel is commonly used in alloys, such as stainless steel, which enhances strength and resistance to corrosion.
This metal is also important in the production of batteries, particularly in rechargeable types like those found in electric vehicles. Nickel is found naturally in the Earth's crust, often in combination with other elements, and is extracted through mining processes.
