Given an unknown substance, find a way by which you can identify whether it is a metal or non metal.

Question

chemistry

Answer 1

just remember these qualities

Physical Properties of Metals:

Luster (shininess)

Good conductors of heat and electricity

High density (heavy for their size)

High melting point

Ductile (most metals can be drawn out into thin wires)

Malleable (most metals can be hammered into thin sheets)

Chemical Properties of Metals:

Easily lose electrons

Corrode easily. Corrosion is a gradual wearing away. (Example: silver tarnishing and iron rusting)

Physical Properties of Nonmetals:

No luster (dull appearance)

Poor conductor of heat and electricity

Brittle (breaks easily)

Not ductile

Not malleable

Low density

Low melting point

note: except for diamonds

Answer 2

Try to prove existence of metallic properties, more then 1 will be required

Conducts electricity

Conducts Heat

Malleable

Ductile

Lustrous when polished

Wide range of melting temperatures but high boiling temperature.

Answer 3

hey brother;

                   THE ELEMENTS PRESENT IN THE LEFT SIDE OF THE PERIODIC TABLE AND THE TRANSITIONAL ELEMENTS (group 3-12 ) ARE METALS AND THE ELEMENTS PRESENT ON THE RIGHT SIDE OF THE PERIODIC TABLE ARE NON METALS

                                            

                  IT'S AN USEFULL METHOD TRY IT

Answer 4

Magnetic attraction?
