Pure gold is too soft, even to be used for medals.
The composition of olympic medals can change from one Olympics to another, such as gold medals that at some Olympics are solid gold but at others have been just gold plated. I would assume however that bronze medals are made of bronze which of course is an alloy of copper and tin.
yes Depends a little on what you mean by "real" silver. It's a lot of silver in them, but there is some percentage of other metals to make the silver more malleable and more suited for making medals of.
Alloys made by mixing metals together often have more desirable properties than pure metals. Pure gold, for example, is very soft and easily damaged. Bronze, an alloy of copper and tin, is also harder than pure copper.
The United States is always on the top three in most medals or gold medasl is every Olympic they participate in.
