What is a physical property?
A characteristic that can be observed or measured
Talk about the physical properties of metals
Shiny High melting and boiling points Solid at room temp Malleable Ductile Good conductors
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
Where are metal elements placed on the periodic table?
On the left hand side
Where are non metals placed on the periodic table?
On the right hand side
What is a chemical property?
A characteristic of a substance that can only be determined by studying its chemical reactions

Talk about how metals and electrons interact with each other
Metals can lose electrons to make positive ions while non-metals can gain electrons to make negative ions
Can non-metals react with each other?
Yes, they create compounds
