Today’s Agenda… Bellringer: Which element is more similar to Argon….Helium or Chlorine? Why? Discuss Venn diagrams/Writing frames Review The Periodic Table Notes on Metals Quiz Tomorrow!

METALS Study Pack #3

Today’s Goals… I can recognize that groups of elements have similar properties. I understand that elements and compounds can be classified by how they react with each other and how they are used.

Metals on the Periodic Table Left of the zigzag line

Physical Properties What is a physical property? Hardness Shininess

Physical Properties Malleability – how well it can be pounded into shapes Ductility – how well it can be made into wire Example: Copper is both malleable and ductile

Physical Properties Conductors Magnetic State of matter  All are solid at room temp. except mercury

Chemical Properties What is a chemical property? Reactivity – if and how quickly it combines with other elements and compounds Some metals react explosively when combined with other elements and compounds

Chemical Properties Some metals react with air to form rust Some metals tarnish

Metals in the Periodic Table Alkali Metals Alkaline Earth Metals Transition Metals Mixed Group Lanthanides and Actinides The metals in these groups have similar properties to each other Change gradually as you move across the periodic table

Alkali Metals Group 1 Very reactive so they are found only in compounds Soft and shiny  Could cut them with a plastic knife! Examples:  Na – found in salt  Li – found in batteries

Alkaline Earth Metals Group 2 Also found only in compounds Fairly hard Grey-white Good conductors of electricity Examples:  Mg – once found in flash bulbs  Ca – found in your bones

Transition Metals Groups 3-12 Even though they are in different families they are very similar to each other Contains most of the familiar metals Hard and shiny Some have unusual colors

Transition Metals Good conductors of electricity React slowly or not at all with air and water Examples:  Au – coins and jewelry  Fe – in your body

Mixed Group Groups Also contains nonmetals and metalloids Not as reactive as those on the left side Examples:  Al  Pb – automobile batteries

Lanthanides and Actinides At the bottom of the periodic table Also known as rare earth elements Soft and malleable Shiny High conductivity Examples:  U – used in nuclear power plants
