  1. Periodic Table Trends and Similarities

  2. Trends of the Periodic Table:At the conclusion of our time together, you should be able to: Give a trend across and down the Periodic Table for metallic characteristics, reactivity, atomic radius and ion radius, electron affinity, ionization energy, electronegativity, density, melting point and boiling point Define each of the terms above Pick the element with the higher trend above from a list of several elements

  3. 15 Helpful Hints On The Lab Report from Mr. T’s Vast Lab Experience!!! Hint #7. In case of doubt, make it sound convincing.

  4. Trends In The Periodic Table: Ionization EnergyAtomic RadiusElectron AffinityElectronegativity, Etc.

  5. Periodic Trends Try to determine the trends by looking at the handouts provided.

  6. Metallic Characteristic Trends Conductivity Shininess Malleability Ductility

  7. Reactivity Of Metals more reactive more reactive

  8. Reactivity Trends

  9. Redneck News: The minimum drinking age in Redneck Country has been raised to 32. It seems they want to keep alcohol out of the high schools.

  10. Atomic Radius Half the distance between the nuclei of two identical atoms that are bonded together. Electron – electron repulsion = larger Proton – electron attraction = smaller Energy level, n, more therefore = larger

  11. Atomic Radius Vs. Atomic Number

  12. Atomic Radius Trends

  13. Periodic Table Trends Answers

  14. Atomic Radius Trends

  15. Questions about teenage men answered by teenage women!!! Q: What do you call a handcuffed boyfriend? A: Trustworthy

  16. Ionic Radius • Cations lose electrons, therefore they tend to be Positive Ions – Metals • Anions gain electrons, therefore they tend to be Negative Ions – Nonmetals

  17. Ionic Radius Trends Electron gain = repulsion = Larger Electron loss = one less energy level = Smaller

  18. Ionic Radius Trends

  19. Happy Birthday Dirge • Happy Birthday, Happy Birthday, • So far Death you have bypassed. • Don’t look back, he’s gaining fast. • Happy Birthday, Happy Birthday!

  20. Electron Affinity The energy change that occurs when a neutral atom acquires an electron. Most electron affinity values are negative. Energy is released from the atom. Atoms that really want another electron tend to be more negative.

  21. Periodic Table Trends Answers

  22. Electron Affinity Trends

  23. Ionization Energy The energy required to remove one electron from a neutral atom. The closer to the nucleus, the harder to pull the electron. The farther away, more interference from other electrons, therefore, the easier it is to pull the electron.

  24. Ionization Energy Vs. Atomic Number

  25. Ionization Energy Trends

  26. Ionization Energy Trends

  27. Electronegativity A measurement of the ability of an atom in a chemical compound to attract electrons.

  28. Generally, • Ionization energy + Electron Affinity = Electronegativity • Most electronegative element – Fluorine (F) • It is assigned the number 4 • All other values are based on this value.

  29. Electronegativity Trends

  30. Electronegativity Trends

  31. Density Mass of a Material Divided by Volume of that Material

  32. Density Trends

  33. Density Trends

  34. Another Redneck Innovation!!!

  35. Boiling Point Temperature at which a system moves from the liquid state to the gaseous state. The external pressure pushing into the liquid is equal to the internal pressure pushing out of the liquid.

  36. Melting Point The temperature at which a solid becomes a liquid. The external pressure pushing into the solid is equal to the internal pressure pushing out of the solid.

  37. Boiling Point Trends

  38. Boiling/Melting Point Trends

  39. Trends of the Periodic Table:Let’s see if you can: Give a trend across and down the Periodic Table for metallic characteristics, reactivity, atomic radius and ion radius, electron affinity, ionization energy, electronegativity, density, melting point and boiling point Define each of the terms above Pick the element with the higher trend above from a list of several elements

  40. Familiar Saying A member of the species commonly designated Homo Sapiens who exhibits an insufficiency of normal sagacity faces imminent separation from his spendable financial assets. A fool and his money are soon parted!!
