• shatters when struck

• able to be drawn into wires

• made of a blend of elements and compounds and are not pure substances because they do not have consistent properties

• a substance that allows an electric current to pass through it

Occurs when one or more substances are changes into new substances with different properties; cannot be undone by physical means
