1. Good conductors of heat and electricity: Metallic minerals have a unique atomic structure where electrons are loosely bound and can move freely throughout the material. This allows them to easily conduct heat and electricity.

2. Malleable and ductile: Metallic minerals are generally malleable, meaning they can be hammered or pressed into different shapes without breaking. They are also ductile, meaning they can be drawn into wires. This is due to the ability of the atoms within the metal to slide past one another without disrupting the metallic bond.
