The Periodic Table! VIDEO:
2
Column = Group or Family
General Information: Column = Group or Family Row = Period
3
METALS VS. NON-METALS
4
Do not conduct electricity Do not react with acids
PROPERTIES OF METALS VS. NON-METALS Lustre Hardness Conductivity Reactivity Metals shiny Malleable, ductile conduct electricity Reacts with acids Non-metals dull Brittle Do not conduct electricity Do not react with acids Metalloids Behave like metals and non-metals
5
Example of Metals and Non-Metals
METALS NON-METALS
