Transcript of "Ions"

  1. 1. The importance of a full outer shell Part 1
  2. 2. Energy Levels <ul><li>The orbitals (or shells) of the atom are not just places for the electrons to hang out, they are quantum energy levels within the atom. </li></ul><ul><li>An atom achieves the greatest energy stability if the outer shell is full. </li></ul>
  3. 3. Inert gases <ul><li>All the inert gases (find these on your PT) have a full outer shell. </li></ul><ul><li>They are very stable and “happy” </li></ul><ul><li>They do not react with any other elements. </li></ul>
  4. 4. How atoms get a full outer shell <ul><li>None of the other elements have full outer shells – they are “unhappy” </li></ul><ul><li>To achieve the “perfect” stable energy state, they can either </li></ul><ul><ul><li>Gain electrons to fill the outer shell </li></ul></ul><ul><ul><li>Lose electrons and shed the outer shell </li></ul></ul>
  5. 5. <ul><li>To gain or lose electrons atoms must interact with each other. </li></ul><ul><li>But first lets have some practice. </li></ul>
