Periodic Block Presentation

  1. 2. Periodic Blocks Chapter 6
  2. 3. Quick review (Stuff u should know already!!!!) <ul><li>What is a valence electron? </li></ul><ul><ul><li>Electrons in the highest principle energy level </li></ul></ul><ul><ul><li>What’s the principle energy level? </li></ul></ul><ul><ul><ul><li>1, 2, 3, 4, 5…. (n) </li></ul></ul></ul><ul><li>Remember Aufbau diagram… </li></ul>
  3. 5. Sublevels <ul><li>How many electrons in s? </li></ul><ul><ul><li>2 </li></ul></ul><ul><li>How many electrons in p? </li></ul><ul><ul><li>6 </li></ul></ul><ul><li>How many electrons in d? </li></ul><ul><ul><li>10 </li></ul></ul><ul><li>How many electrons in f? </li></ul><ul><ul><li>14 </li></ul></ul>
  4. 6. Observations???
  5. 7. Observations <ul><li>What was the connection between period number and the elements that you were assigned? </li></ul><ul><ul><li>Valence electrons? </li></ul></ul><ul><ul><li>Principle quantum number? </li></ul></ul><ul><ul><li>Sublevel? </li></ul></ul><ul><ul><li>Orbital? </li></ul></ul><ul><ul><li>Partially filled or completely filled? </li></ul></ul>
  6. 8. Period # & Valence electrons <ul><li>The energy level of the valence electrons of an element tell you the period that it will be in (the row!!!) </li></ul><ul><li>Remember, energy level is your principle quantum number (n) </li></ul>
  7. 9. S-Block <ul><li>Groups 1a and 2a </li></ul><ul><li>Valence electrons occupy only s-orbitals </li></ul><ul><li>Group 1a  partially filled s </li></ul><ul><li>Group 2a  completely filled s </li></ul><ul><li>How many max electrons can an s-orbital hold? </li></ul><ul><li>Soooo how many groups are going to makeup the s-block? </li></ul><ul><ul><li>2 </li></ul></ul>
  8. 10. So what sublevel do we go to after we fill an s-sublevel? <ul><li>P-sublevel…. </li></ul>
  9. 11. P-block <ul><li>How many orbitals does the p sublevel have? </li></ul><ul><ul><li>3…remember, three lines _ _ _ </li></ul></ul><ul><li>Do you think we will have more or less electrons here than the s-block? </li></ul><ul><ul><li>MORE!!! </li></ul></ul><ul><li>Groups 3a thru 8a </li></ul><ul><li>Why is there no p-block elements in period 1? </li></ul><ul><ul><li>Because at energy level (principal quantum #) 1, we do not have any p sublevels </li></ul></ul><ul><li>How many max electrons can a p-sublevel hold? </li></ul><ul><li>SO how many groups is the p-block going to have? </li></ul><ul><ul><li>6 </li></ul></ul>
  10. 12. Noble gases in P-block <ul><li>What do we notice about their s and p orbital??? </li></ul><ul><ul><li>They are completely full </li></ul></ul><ul><ul><li>So they are stable…no chemical reaction </li></ul></ul><ul><ul><li>Important later when we talk about ions…. </li></ul></ul>
  11. 13. Welcome to the D-Block! <ul><li>Contains transition metals </li></ul><ul><li>How many elements are going to reside on the D-block? </li></ul><ul><ul><li>Lots! </li></ul></ul><ul><li>There are many exceptions but…. </li></ul><ul><ul><li>Filled outermost s-orbital of energy level n </li></ul></ul><ul><ul><li>Filled or partially filled d-orbitals of energy level n-1 </li></ul></ul><ul><li>What happens to the d orbitals as we move across a period? </li></ul><ul><li>How many groups do you think are going to make up the d-block? </li></ul><ul><ul><li>Hint: How many electrons can a d-sublevel hold? </li></ul></ul><ul><ul><li>10!!!! </li></ul></ul>
  12. 14. F-Block elements…uh-oh…. <ul><li>What do we have left on the periodic table? </li></ul><ul><ul><li>Lanthanide and actinide series (inner transition metals) </li></ul></ul><ul><ul><li>They fall into periods 6 and 7 </li></ul></ul><ul><li>Characterized by: </li></ul><ul><ul><li>Filled or partially filled outer most s-orbital </li></ul></ul><ul><ul><li>Filled or partially filled 4f and 5f orbitals </li></ul></ul><ul><li>Sorry guys…these electrons in the f-block do not fill in a predictable manner </li></ul><ul><li>How many columns are going to make up the f-block? </li></ul><ul><ul><li>Hint: How many electrons can an f-sublevel hold? </li></ul></ul><ul><ul><li>14!!!! </li></ul></ul>
  13. 15. So…. <ul><li>Now we see why the periodic table has that funny shape! </li></ul><ul><li>We can now also do electron notations in less tedious manner! </li></ul>
  14. 18. Tell me what happens…. <ul><li>To the principle energy levels as we move down a period? </li></ul><ul><ul><li>Princ. E level increases </li></ul></ul><ul><li>To the number of sublevels containing electrons as we move down a period? </li></ul><ul><ul><li>Increases too!!! </li></ul></ul>
  15. 22. Practice problems!!! <ul><li>Periodic tables away!!! </li></ul><ul><li>Tell me the group, period, and block of an atom with the following electron configurations: </li></ul><ul><ul><li>[Ne]3s 2 </li></ul></ul><ul><ul><li>[He]2s 2 </li></ul></ul><ul><ul><li>[Kr]5s 2 4d 10 5p 5 </li></ul></ul>
  16. 23. Answers <ul><ul><li>[Ne]3s 2 </li></ul></ul><ul><ul><ul><li>Group 2a </li></ul></ul></ul><ul><ul><ul><li>Period 3 </li></ul></ul></ul><ul><ul><ul><li>S-block </li></ul></ul></ul><ul><ul><li>[He]2s 2 </li></ul></ul><ul><ul><ul><li>Group 2a </li></ul></ul></ul><ul><ul><ul><li>Period 2 </li></ul></ul></ul><ul><ul><ul><li>S-block </li></ul></ul></ul><ul><ul><li>[Kr]5s 2 4d 10 5p 5 </li></ul></ul><ul><ul><ul><li>Group 7a </li></ul></ul></ul><ul><ul><ul><li>Period 5 </li></ul></ul></ul><ul><ul><ul><li>p-block </li></ul></ul></ul>
  17. 24. More problems… <ul><li>Write the electron configuration for the following elements: </li></ul><ul><ul><li>The group 4b element in the fifth period? </li></ul></ul><ul><ul><li>The group 1a element in the seventh period? </li></ul></ul>
  18. 25. Answers <ul><ul><li>The group 4b element in the fifth period? </li></ul></ul><ul><ul><ul><li>Zirconium </li></ul></ul></ul><ul><ul><ul><li>[Kr]5s 2 4d 2 </li></ul></ul></ul><ul><ul><li>The group 1a element in the seventh period? </li></ul></ul><ul><ul><ul><li>Francium </li></ul></ul></ul><ul><ul><ul><li>[Rn]7s 1 </li></ul></ul></ul>
  19. 26. REPRESENTATIVE BLOCK PARTY!!! <ul><li>Make cube…how many sides is this? </li></ul><ul><ul><li>6 </li></ul></ul><ul><li>Side 1…Artistically symbol of element with vitals </li></ul><ul><li>Side 2…Label the elements group </li></ul><ul><li>Side 3…Write the element’s electron configuration </li></ul><ul><li>Side 4…Illustrate/describe Properties of the element </li></ul><ul><li>Side 5…Illustrate/describe Uses of element </li></ul><ul><li>Side 6…Important compounds this element is found in </li></ul>
  20. 28. Periodic Trends <ul><li>What’s a trend </li></ul>
