TRANSCRIPT
- 1. The Periodic Table
2. Mendeleev 3. 4. Moseley 5. Row Series Period 6. Column GroupFamily 7. Periodic Law 8. When elements are arranged by atomic number, there is a periodic pattern in their physical and chemical properties. 9. Valence Electrons 10. 11. Periodic Trends 12. Atomic Radii
- Half of the distance between two bonded nuclei
Down Group Across Series Increases Shielding Decreases Greater nuclear charge as well as more valence electrons. 13. Ionization Energy
- The energy required to remove the outermost electron
Down Group Across Series Decreases Shielding Increases Moving toward non-metals that seek stability of octet by gaining electrons 14. Electronegativity
- A measure of an atoms attraction toward electrons while in a chemical bond
Down Group Across Series Decreases Shielding Increases Moving toward non-metals that seek stability of octet by gaining electrons
