Applied Chapter 4.2 : Tour of the Periodic Table

  1. 1. Chapter 4.2<br />Tour of the Periodic Table<br />
  2. 2. Objective 1:<br />Locate the different families of main-group elements, on the periodic table, describe their characteristic properties, and relate their properties to their electron configurations.<br />

  7. 7. Has s2 configuration
  8. 8. Properties of Group 18 Noble gases</li></li></ul><li>S-block Elements: Group 1 & 2<br />1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18<br />Group 1 – Alkali metals<br />Properties –<br /><ul><li> silvery
  9. 9. soft metal
  10. 10. very reactive
  11. 11. not found in nature as free elements
  12. 12. react strongly with water</li></ul>Group 2 – Alkaline earth metals<br />Properties –<br /><ul><li> silvery
  13. 13. harder, denser and stronger than alkali metals
  14. 14. Reactive, but not as much as alkali
  15. 15. not found in nature as free elements</li></li></ul><li>P-block elements: group 13-18<br />Main-group elements<br />P-block elements together with s-block elements<br />Electron configurations<br />Group<br /> 13 ns2np1<br />14 ns2np2<br />15 ns2np3 <br /> 16 ns2np4<br /> 17 ns2np5<br /> 18 ns2np6<br />p-block <br />s-block <br />ns2np6<br />Stable Noble gas configuration<br />
  16. 16. P-block elements: group 13-18<br /><ul><li>Group 17
  17. 17. Halogens
  18. 18. Properties
  19. 19. Most reactive nonmetal
  20. 20. React vigorously with most metals
  21. 21. Some are gases at room temperature</li></ul>Total number of electrons in highest energy level <br />Group number minus 10<br /><ul><li>Properties vary greatly
  22. 22. Metals/metalloids/</li></ul>nonmetals<br />p-block <br />
  23. 23. Objective 2:<br /><ul><li>Locate metals on the periodic table, describe their characteristic properties, and relate their properties to their electron configurations.</li></ul>d – block elements: Groups 3 - 12<br />Transition Elements<br />First appears when n =3<br /><ul><li>Properties:
  24. 24. Good conductors of heat and electricity
  25. 25. High luster
  26. 26. Less reactive than alkali and alkaline earth metals
  27. 27. Some are so unreactive, they don’t form compounds
  28. 28. Exist in nature as free elements</li></ul>d-block <br />Au<br />Zn<br />Cu<br />Hg<br />
  29. 29. f-block elements: Lanthanide and Actinides<br />Wedged between groups 3 and 4 in the sixth and seventh periods<br />14 f-block elements in each of the series<br />Actinides are all radioactive<br />Only first 4 actinides have been found naturally on earth<br />Lanthanides are shiny metals similar to alkaline earth metals<br />f-block <br />Samarium<br />Uranium<br />
  30. 30. Lanthanides and Actinides<br />Lanthanides – 14 elements with atomic number from 58 to 71<br />Cerium to Lutetium (Top row – f-block)<br /><ul><li>Actinides – 14 elements with atomic number from 90 to 103
  31. 31. Thorium to Lawrencium ( Bottom row – f-block)
  32. 32. To save space – both were set off below main portion of periodic table
