Metals

• Where are metals located on the periodic table?

  On the left and center of the periodic table
• Where are non-metals located on the periodic table?

  On the right-hand side of the periodic table
• How can metals be categorized on the periodic table?

  • Highly reactive metals in groups one and two
  • Transition metals in the center of the periodic table
• Why are noble gases considered unreactive?

  Because they have a full outer energy level
• What happens to metals when they react?

  They lose electrons to achieve a full outer energy level
• What electronic structure do metals achieve when they react?

  A full outer energy level like that of a noble gas
• What is the electronic structure of lithium?

  Three protons and three electrons
• What is the electronic structure of sodium?

  Eleven protons and eleven electrons
• What occurs to lithium and sodium when they react?

  • They lose their one outer electron
  • Achieve a full outer energy level
• What is the charge of a lithium ion after it loses its outer electron?

  One positive charge
• How is a lithium ion represented?

  By drawing square brackets around the ion and writing the overall charge in the top right corner
• What is the overall charge of a sodium ion?

  One positive charge
• What happens to the charge of a metal atom when it loses electrons?

  • The atom becomes an ion
  • It has an overall positive charge
• What is the charge of a barium ion after it loses its outer electrons?

  Two positive charges
• How do metals form positive ions?

  • Metals lose their outer electrons
  • Resulting in an overall positive charge
