I have compiled a list of sources for the elements that are available to the amateur chemist. Nickel will be discussed here.

 

Nickel is a hard golden-silver corrosion-resistant metal. It forms green and blue compounds that are predominantly divalent. Nickel can cause allergic reactions, while its salts are considered Category 1 carcinogens (definitely carcinogenic). Nickel is used as a 25% nickel-75% copper alloy in the U.S. nickel. Some Canadian coins are made of pure nickel, which is ferromagnetic (strongly attracted to a magnet).

 

In element form: Some objects such as magnets are nickel plated. Obtain a pure 100% nickel coin, such as an old Canadian nickel. Precipitate nickel metal from a solution of its ion by reacting it with magnesium. A U.S. nickel is 25% nickel. 18/10 stainless steel has 10% nickel in it. Nichrome has about 80% nickel. Alnico magnets contain from 15-26% nickel. Cheap spark plugs' ground electrodes can be nickel plated or solid nickel.

 

In compound form: Nickel metal-hydride and nickel-cadmium batteries have nickel oxide hydroxide in them.

 

Here is an old Canadian coin, made of pure nickel metal.
