Solid platinum is a silvery-white metal:



It’s crystal form has what’s called a "cubic-closest-packed" structure. In this structure, each atom is like the corner of a cube, and extra atoms are nestled into each side of the cube. Here’s two pictures of this:



In this picture (above), the atoms are really small, so it’s easy to see what the structure looks like.



In reality, the atoms are packed really closely together. This picture shows this pretty well.

Thanks to for these pictures.
