What are the Physical Properties of Metals?
Physical Properties of Metal. 1. Metals have a metallic lustre. Collect some pieces of some common metals, like iron, copper, aluminum and magnesium. Observe their appearance and how they reflect light. The reflection is different for each metal. The shine of light on a metal is called metallic luster.
Sep 10, 2002· Carbon is present in two natural crystalline allotropic forms—graphite and diamond—each with its own separate crystal structure and properties. The term graphite is derived from the Greek word “graphein,” which means to write. The material is typically grayish-black in color, opaque, and has a radiant black sheen.
