Exploring Periodic Trends in Chemical Elements

Discover the fascinating world of chemical periodicity, encompassing group trends, transition metals, inner transition metals, main block elements, hydrogen, alkali metals, alkaline earth metals, halogens, and noble gases. Uncover the characteristics of transition and inner transition metals such as multiple energy levels for valence electrons and properties like ductility, malleability, and electrical conductivity. Learn about the Main Block Elements, including the abundance and flammability of hydrogen, the reactivity of alkali metals, and the characteristics of alkaline earth metals. Explore the highly reactive halogens and the unreactive noble gases with eight valence electrons. Delve into periodic trends like electronegativity, electron affinity, ionization energy, atomic radii, and the shielding effect. This comprehensive guide offers a summary of the essential concepts in chemical periodicity, providing a wealth of knowledge for chemistry enthusiasts. The end of chemical periodicity marks a captivating journey through the elements, illustrated with images sourced from the internet.

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.
