Different types of floor hardners

Difference Between Metallic Minerals and Non-Metallic Minerals:

Properties	Metallic Elements	Non-metallic Elements
Definition	Metallic minerals contain metal elements in their chemical formula	Non-Metallic Minerals do not contain metal elements in their inorganic chemical formula.
Example	Chalcopyrite, Iron, Copper, Gold, etc.	Clay, Diamond, Dolomite, Gypsum, Mica, Amethyst and Quartz, etc.
Extraction of Material	Metals can be extracted by melting the metallic minerals.	Non-metallic minerals do not yield new products upon melting.
Derivation	They are associated with igneous rocks.	Are associated with sedimentary rocks.
Nature	Metals are generally hard solid and vapourize only at high temperature.	Non-metals are generally soft and usually gases or liquids.
Lustre	Metals have a lusture called metallic lusture and can be polished.	Non-metals lack luster.
Melting & boiling point	Their melting and boiling points are high (except alkali metals and Hg).	Non-metals usually have low melting and boiling points.
Density	Metals have high density except alkali metals like Na, K etc.	Non-metals generally have low density.
Malleability & ductility	Metals are generally malleable and ductile and have very high tensile strength.	Non-metals are non-malleable and non-ductile.
Formation of alloy	Metals form alloys and amalgams. Bronze is an alloy of Copper, Tin & Zinc. Sodium amalgam is an alloy of Mercury & Sodium.	Non-metals do not form alloys.
Brittle	Metals are hard, but not brittle.	Non-metals are brittle in nature.
Conduction of heat & electricity	Metals are generally good conductors of heat and electricity.	Non-metals are bad conductors of heat and electricity.
Solubility in water / liquid	Metals do not generally dissolve in liquids except by chemical reaction.	They are generally soluble in water or other solvents and do not react with them chemically i.e. no chemical reaction takes place.
Sound when hit	They make a ringing sound (they are sonorous)	They make a dull sound
