Platinum can bond with other metals such as gold or iron, forming a metallic bond. If it bonds with a nonmetal, it is an ionic bond.
Platinum is a metal that resembles silver. It is similar to gold in that it does not erode. This metal was first brought to Europe in 1750. However, it was used for almost 2,000 years before that by the Egyptians. Platinum is now used for many different reasons. The metal can be found in catalytic converters for cars because it has a high melting point. Many computers have platinum components. Platinum is also used for many jewelry pieces.
