Introduction to Periodic Table Groups and Periods

Understand the concepts of groups and periods in the Periodic Table, including trends in atomic radius, ionization energy, and electronegativity. Learn about metals, nonmetals, and elements in different families. Engage in hands-on activities to explore the characteristics of elements.

  1. 2/14 DO NOW • What is a group in the Periodic Table? • 2. What is a period in the Periodic Table? • 3. What is the group and period number for Pt? • 4. Which Periodic Trend identifies an atom’s relative attractions to electrons? • 5. Which element has a larger atomic radius, F or N? • 6. Which element has a greater ionization energy, H or Cs? Grab binders & handouts, begin the Do Now

  3. Atomic Radius (AR) • - Definition: size of the atom • Ionization Energy (IE) • - Definition: how much energy it takes to remove an e- from an atom • Electronegativity (EN) • - Definition: atom’s attraction/pull on e- Overview of the Periodic Trends

  4. Try the following… • What element is found in Group 11, Period 5? • What element is found in Group 16, Period 3? • What is the group and period number for Potassium (K)? • Which element is smaller, Chlorine (Cl) or Iodine (I)? • Which element is more electronegative, Cesium (Cs) or Polonium (Po)? • Which element requires more energy to remove an electron, Strontium (Sr) or Magnesium (Mg)? Periodic Trends Check In

  5. Periodic Trends RAFTS Application

  6. As you listen/read through the samples….. • Identify words that convey the strong verb - ATTRACTION RAFTS Word Choice

  7. Periodic Trends RAFTS Application

  8. The Periodic Table is split up into two main categories: Metals & Nonmetals • Characteristics of Metals: • Characteristics of Nonmetals: • *Elements in the same family have similar chemical characteristics Periodic Table Families: Key Points

  9. Nonmetals

  10. Metal Groups: • Group 1 – Alkali Metals • Group 2 – Alkaline Earth Metals • Group 3 – Transition Metals • Nonmetals Groups: •  Group 7 – Halogens •  Group 8 – Noble Gases Periodic Table Families

  11. As a group you have 17min to complete the following… • Determine how you will present to the class (organize the layout and what you may need) • Begin research & completing individual element profiles Periodic Table Families Group Project
