Properties of metallic substances
Metals are often shiny
The free electrons in metallic substances reflect light and make them shiny.

Metallic substances are malleable
Metallic bonding allows molecules to slide over one another. This makes metals malleable which means they can be bent, hammered, pressed or rolled into shape without breaking or cracking.
