Metals and their ores
Some examples of metals are: Aluminium, Copper, Iron, Tin, Gold, Lead, Silver, Titanium, Uranium, and Zinc. 2.2. Non-Metals. Non-Metals are not malleable or ductile, and they are poor conductors of heat and electricity. At room temperature, most non-metals are gases that do not conduct electricity, such as oxygen, hydrogen, and chlorine.
