  1. The Periodic Table GROUPS

  2. ALKALI METALS • very reactive metals • Hydrogen is not a member, it is a non-metal • 1 electron in the outer shell • combine violently with water (stored in oil) • Only compounds in nature • soft and shiny (can be cut with a knife)

  3. ALKaLINEEARTH METALS • very reactive (less reactive than alkali metals) • -only compounds in nature • -hard, grey-white, good conductors • 2 electrons in the outer shell

  4. TRANSITION METALS • ductile and malleable, and conduct electricity and heat • groups 3-12 • bridge between very reactive and less reactive elements

  5. METALLOIDS • have properties of both metals and non-metals. • semiconductor/insulator of electricity

  6. HALOGENS • exist in all three states of matter • -dangerous to humans • -poisonous and highly corrosive

  7. NOBLE GASES • do not form compounds easily • found in the atmosphere • -chemically stable/not reactive • Happy Elements (Full outer shells)

  8. RARE EARTH ELEMENTSLanthanides & Actinides
