Properties of compounds

What phase are each compound at room temp?

Ionic- solid at room temp

Covalent- gases or liquid at room temp

Metallic- solid at room temp

What is the melting point of each compound

Ionic- very high

Covalent- low

Metallic- High

What is the boiling point of each compound?

Ionic- very high

Covalent- low

What compounds are easy to turn into a gas?

Covalent- yes

Ionic & metallic - no

When the compounds are pounded, what happens?

Ionic- compounds fracture

Covalent- nothing, they can’t be pounded as they are gases and liquids

Metallic:

-metallablity (they are easy to pound into shape)

-ductility (they can be pulled into a wire shape)

Can the compounds conduct Electricity?

Ionic- ONLY if they dissolve in water or melted to plasma, the yes they can conduct electricity

Covalent- no

Metallic- yes

What is the smallest unit of each compound called?

Ionic- formula

Covalent- molecule

Metallic- atom

What is the structure of the solid?

Ionic- crystalline structure

Covalent- no structure because they aren’t solid

Metallic- sea of electrons

What is happening with the electrons in each compound?

Ionic- electrons are being transferred

Covalent- electrons are being shared

Metallic- electrons are being shared in the sea of electrons
