1
What is a physical property?
A characteristic that can be observed or measured
2
Talk about the physical properties of metals
Shiny
High melting and boiling points
Solid at room temp
Malleable
Ductile
Good conductors
3
Talk about the physical properties of non metals
Dull
Usually low melting and boiling points
Half are solid and half are gas at room temp
Brittle
Non ductile
Poor conductors
