Lecture 6.2- e- configs and the Periodic Table

  1. 1. Lecture 6.2-e- configs & the Periodic Table
  2. 2. Electron configurations can beshortened by writing the symbolof the previous noble gas inbrackets to represent the insideelectrons. Shortened 1s2 [He]2s22p6 [Ne]3s23p6 [Ar]3d104s24p6
  3. 3. Electron Configurations in Groups Elements can be sorted into noble gases, representative elements, transition metals, or inner transition metals based on their electron configurations.
  4. 4. Electron Configurations in GroupsNoble gases (Group 8A) havefull outer energy levels.Usually an s2p6 configuration.Helium is full with s2
  5. 5. Electron Configurations in Groups
  6. 6. Electron Configurations in GroupsThe Representative Elements(Groups 1,2,13-18 or groups 1A-8A)
  7. 7. Electron Configurations in GroupsThe Representative Elements(Groups 1,2,13-18 or groups 1A-8A) For representative elements s and p sublevels of the highest occupied energy level are not filled.
  8. 8. Electron Configurations in GroupsThe Representative Elements(Groups 1,2,13-18 or groups 1A-8A) For representative elements s and p sublevels of the highest occupied energy level are not filled. The group number equals the number of electrons in the highest/outermost energy level.
  9. 9. Electron Configurations in GroupsAlkali metals (Group 1A) have oneelectron in the highest occupiedenergy level. s1 configuration
  10. 10. Electron Configurations in GroupsAlkaline earth metals (Group 2A)have two electrons in the highestoccupied energy level. s2Halogens(Group 7A) have an s2p5configuration.
  11. 11. Transition ElementsTransition Elements There are two types of transition elements—transition metals and inner transition metals. They are classified based on their electron configurations.
  12. 12. Transition Elements
  13. 13. Transition ElementsIn transition metals, the highestenergy electrons are found ininner d orbitals.
  14. 14. Transition ElementsIn transition metals, the highestenergy electrons are found ininner d orbitals.In atoms of an inner transition metal,the highest occupied s sublevel and aninner f sublevel contain electrons.
  15. 15. PeriodsThe period number tells which energylevel the outside electrons are in.Ex. 3rd period sodium(Na) is [Ne]3s1 4th period potassium(K) is [Ar]4s1
