Physical Properties of Metals and Non Metals

Metals and nonmetals are two major groups of elements that have different physical properties.

7.P.2B.1:

Analyze and interpret data to describe substances using physical properties (including state, boiling/melting point, density, conductivity, color, hardness, and magnetic properties) and chemical properties (the ability to burn or rust).

I Can Statement

I can describe substances using physical and chemical properties.

Essential Question

How can physical and chemical properties be used to describe substances?

Open Ended

How can you determine if an unknown substance is a metal?

Multiple Select

Select the 2 metal examples

LUSTER

Having a shiny surface or reflecting light brightly

Conductivity

Heat and electricity move through them easily

Density

Heavy for their size

Malleable

Ability to be hammered into different shapes

Will it bend?

Ductable

Ability to be drawn into a wire

Will it stretch?

Open Ended

Which physical property would be most useful in determing if a substance is a metal or nonmetal? and why?

Non metals can be identified or classified by the following physical properties.

• Dull

• Nonconductors

• Brittle

Dull

Not shiny

Nonconductors

Heat and electricity do not move through them easily

Brittle

Breaks or shatters easily (solids)
