  • 1. 3.3 The Periodic Table and the Elements Dr. Fred Omega Garces Chemistry 100 Miramar College 3.3 Periodic Table 9.17.00 1:37 PM
  • 2. The Periodic Table and the Elements What is the periodic table ? What information is obtained from the table ? How can elemental properties be predicted base on the PT ? 3.3 Periodic Table 9.17.00 1:37 PM
  • 3. Dmitri Mendeleev (1869) In 1869 Mendeleev and Lothar Meyer (Germany) published nearly identical classification schemes for elements known to date. The periodic table is base on the similarity of properties and reactivities exhibited by certain elements. Later, Henri Moseley ( England,1887-1915) established that each elements has a unique atomic number, which is how the current periodic table is organized. http://www.chem.msu.su/eng/misc/mendeleev/welcome.html 3.3 Periodic Table 9.17.00 1:37 PM

  • 5. Periodic Table Expanded View The way the periodic table usually seen is a compress view, placing the Lanthanides and actinides at the bottom of the stable. The Periodic Table can be arrange by subshells. The s-block is Group IA and & IIA, the p-block is Group IIIA - VIIIA. The d-block is the transition metals, and the fblock are the Lanthanides and Actinide metals 3.3 Periodic Table 9.17.00 1:37 PM

Periodic Table: electron behavior The periodic table can be classified by the behavior of their electrons West (South) 1 East (North) METALS Alkali Alkaline Transition These elements tend to give up e - and form CATIONS 1 IA Mid-plains METALLOID NON-METALS Noble gas Halogens Calcogens These elements tend to accept e - and form ANIONS These elements will give up e- or accept e- 2 IIA 13 IIIA 14 IVA 18 VIIIA 15 VA 16 VIA 17 VIIA 2 3 3 IIIB 4 IVB 5 VB 6 VIB 7 VIIB 8 9 VIIIB 10 11 IB 12 IIB 4 5 6 7 3.3 Periodic Table 9.17.00 1:37 PM
  • 15. 2. Trend in Atomic Radius Atomic Radius: The size of at atomic specie as determine by the boundaries of the valence e-. Largest atomic species are those found in the SW corner since these atoms have the largest n, but the smallest Zeff. 3.3 Periodic Table 9.17.00 1:37 PM
  • 16. 3. Trend in Ionization Potential Ionization potential: The energy required to remove the valence electron from an atomic specie. Largest toward NE corner of PT since these atoms hold on to their valence e- the tightest. 3.3 Periodic Table 9.17.00 1:37 PM
  • 17. 4. Trend in Electron Affinity Electron Affinity: The energy release when an electron is added to an atom. Most favorable toward NE corner of PT since these atoms have a great affinity for e-. 3.3 Periodic Table 9.17.00 1:37 PM
  • 18. Summary of Trend Periodic Table and Periodic Trends 1. Electron Configuration 3. Ionization Energy: Largest toward NE of PT 4. Electron Affinity: Most favorable NE of PT 2. Atomic Radius: Largest toward SW corner of PT 3.3 Periodic Table 9.17.00 1:37 PM
  • 19. Summary Periodic Table: Map of the Building block of matter Table Type: Metal, metalloid and Nonmetal Type Groupings: Representative or main, transition and Lanthanide/Actanides Family: Elements in the same column have similar Family chemical property because of similar valence electrons Alkali, Alkaline, chalcogens, halogens, noble gases Period: Elements in the same row have valence electrons in the same shell. 3.3 Periodic Table 9.17.00 1:37 PM
