Presentation Transcript

  1. CHEMICAL PERIODICITY

  2. Group Trends • Transition Metals • Innertransition Metals • Main Block Elements • Hydrogen • Alkali Metals • Alkaline Earth Metals • Halogens • Noble Gases

  3. Transition & Innertransition Metals Innertransition Metals Transition Metals • Valence electrons found on more than one energy level • Ductile, malleable, and conductselectricity • Lanthanoids • Actinoids

  4. Main Block ElementsHydrogen • Most abundant element in the universe • Colorless gas • Dangerous due to its flammability (used to be used in hot air balloons)

  5. Main Block ElementsAlkali Metals • Most reactive metals • Found in Group 1 • One valence electron • Softer than other metals • Malleable, ductile, and good conductors • Explode in cold water

  6. Main Block ElementsAlkaline Earth Metals • Reactive metallic elements • Found in Group 2 • Two valence electrons • Not found free in nature

  7. Main Block ElementsHalogens • Very reactive non-metallic elements • Found in Group 17 • Seven valence electrons • Group has all 3 states of matter

  8. Main Block ElementsNoble Gases • Unreactive gases • Found in Group 18 • Eight valence electrons • Very stable

  9. PERIODIC TRENDS • Electronegativity • Electron Affinity • Ionization Energy • Atomic Radii (Size) • Shielding Effect

  10. Summary of Periodic Trends

  11. THE END OF CHEMICAL PERIODICTY Just a few pictures that I found off the internet.
