Properties of Nickel: From Coins to Alloys and Beyond

Nickel, with atomic number 28, is a lustrous metal used since ancient times. It was classified as an element in 1751. Nickel is widely used in coinage, often alloyed with other metals due to its high cost. It forms alloys like stainless steel and alnico magnets, and is used in batteries, guitar strings, and plumbing. Nickel's resistance to corrosion makes it valuable in marine applications. While not essential for humans, it aids plant growth. Nickel is safe in small amounts and is found in everyday products like shampoos.
