A Babbitt metal is a soft white alloy of variable composition, used in bearings to diminish friction. Such compositions include nine parts tin to one part copper, or fifty parts tin to five antimony and one copper.
Platinum is the the metal known as white gold.
No. It is a physical change because the chemical composition of the metal remains the same.

The properties of a metal are of follows, a pure chemical composition, a pure chemical composition is a element, or a compound in pure form. As well as a metallic luster (when it is shiny and if melted or filed flat it looks like a mirror. Now pure chemical composition is hard to test with solid metal, but a metallic luster should do the trick usually, and if it is being melted, than you should see that is is a pure chemical composition by looking if parts of it have different melting speeds.
