metals

• Where are metals located on the periodic table?

  On the left and center of the table
• What are the two broad categories of metals?

  Highly reactive metals and transition metals
• Which groups contain highly reactive metals?

  Groups one and two
• How do transition metals compare in reactivity to metals in groups one and two?

  They are generally less reactive
• What do noble gases have that makes them unreactive?

  A full outer energy level
• What happens when metals react?

  They lose electrons to achieve stability
• What electronic structure do metals achieve when they react?

  Same as a group zero noble gas
• Why are lithium and sodium in group one?

  They have one electron in their outer level
• What happens to the charge of lithium when it loses an electron?

  It becomes one positive
• What is an ion?

  An atom with an overall charge
• How is an ion represented?

  With square brackets and charge
• What are the key facts about metals and their reactions?

  • Metals are on the left and center of the periodic table.
  • They lose electrons to achieve a full outer energy level.
  • Metals always form positive ions.
