Platinum is even rarer than gold, and that makes this metal just as precious. Besides a source of wealth, platinum is used to make jewelry, electronics, magnets, medicine, and other valuable objects. This remarkable element and important science concepts are explored throughout this book. Graphic organizers, colorful photographs, and fun fact boxes add support to the text.
