The zinc oxidizes on the other nail, but the oxidation results in a protective coating of zinc oxide forming on the zinc.

How are batteries designed The farther apart two metals are in Table 17.1, the larger the voltage of a battery that can be constructed from them. If you wanted to make a high-voltage battery to power your radio, you would choose metals that are far apart in the table. A copper penny with an iron nail will yield a larger voltage than a penny with a piece of nickel because copper is farther away from iron in the table than it is from nickel.

Oxygen introduced the chemistry of copper into this evolutionary fluidity. A home experiment shows how copper has a special relationship with oxygen. For this experiment, you need a penny minted before 1982 (before that, pennies were real copper now, they re mostly zinc). Heat the penny up, and dangle it on a wire over a few tablespoons of nail polish remover, which contains acetone. In a few seconds, the penny will glow as red as molten iron. But there s little danger so long as you don t catch the acetone on fire or touch the penny. Once the penny cools off it will be as good as new, even cleaned up by the ordeal.
