You are given two samples. How do you distinguish which one is metal and which is non-metal?

Physical and Chemical Properties of the metals helps us to differentiate between metals and non-metals

PHYSICAL PROPERTIES

A) Metals are commonly hard while non-metals are soft so we can touch the given sample in order to know which one is metal and which one is not.

B) We will strike the given sample and if that produces high pitch sound then it is metal otherwise non-metal.

Chemical Properties

We know that metals are susceptible to rusting but non-metals are not for example when we place the given sample in the air in contact with moisture, if the sample gets rusted then it is metal.
