  1. ChemistryUnit 4 – Ionic Bonds Lesson 3 – The Periodic Table Book Section: 6.2 Objective: SWBAT classify the periodic table by column. Do Now: What do lithium, sodium, and potassium have in common?

  2. Periodic Law • Rows of the periodic table are called periods. • Columns of the periodic table are called groups, or families. • Groups tend to have similar chemical properties.

  3. S-Block: Group 1A: Alkali Metals • Very shiny, reactive metals • Oxidize in air very quickly • VIDEO: Sodium Lithium Potassium Sodium Rubidium

  4. S-Block: Group 2A – Alkaline Earth Metals • Very high melting points (earth metals) • Named after their oxides that are basic (or alkaline) in solution • Less reactive than alkali metals, but retain similar reactivities – need more energy to react.

  5. P-Block: Group 3A – Boron Group • Edges the metal-nonmetal line • Boron group has poor metals and metalloids. Boron Gallium Aluminum Thallium Indium

  6. P-Block: Group 4A – Carbon Group • Most versatile bonding group • Organic chemistry & semiconductors live here Silicon Carbon Tin Germanium Lead

  7. P-Block: Group 5A – Nitrogen Group • Mostly nonmetals • Mixture of gases and solids Phosphorus Nitrogen (liquid) Antimony Arsenic Bismuth

  8. P-Block: Group 6A – Chalcogens • Mostly nonmetals • React strongly with metals Sulfur Oxygen (liquid) Selenium Tellurium

  9. P-Block: Group 7A – Halogens • Also called halides • Very reactive, so much that they react with themselves • Solid, liquid, and gases in family Chlorine Fluorine Bromine Iodine

  10. P-Block: Group 8A – Noble Gases • Nonreactive • Have full valence shell • All gases (no interactions between molecules) Neon Helium Argon Krypton Xenon

  11. D-Block: Transition Metals • “Outermost electrons” in the d-subshell • The d-subshell’s electron transitions are in the visible spectrum • Which makes solutions of transition metals have pretty colors • DEMO: Transition metal solutions Gold Copper Tungsten Chromium Cobalt

  12. F-Block: Rare Earth Metals • “Outermost electrons” in the f-subshell • When atoms get this heavy, the nuclei become unstable and decay – radioactive • Lanthanides – top row of f-block • Actinides – bottom row of f-block Cerium Uranium Americium Plutonium Holmium

  13. HW 4-1 Due Wednesday • This week: • Tuesday: Keystone Testing (2nd), Go over Atom Exam (4th) • Wednesday: The Periodic Table (6.2), HW 4-1 Due • Thursday: Electron Configurations and the Periodic Table (6.2) • Friday: Periodic Properties Lab, HW 4-2 Due
