Extension: Get the Gizmo ready: • Select Lithium (Li) from the Select a metal list. Chemical families • You will need a periodic table for this activity. Introduction: The periodic table arranges elements by size and property. The vertical columns represent chemical families, or groups of elements with similar chemical properties. Question: How are elements arranged into chemical families? 1. Observe: Drag the nonmetal into the trash ( ) so there is only the one lithium atom visible. A. How many valence electrons does lithium have? B Now look at your periodic table. Find lithium (Li) in the first column. Other than lithium, which element from the Gizmo is also in this column? C. Choose this element. How many valence electrons does this element have? 2. Gather data: Four other pairs of elements in the same chemical family are listed below. List the number of valence electrons in each element. Nitrogen Phosphorus Oxygen Fluorine Sulfur Chlorine Beryllium Magnesium 3. Analyze: What pattern do you see? 4. Make a rule: Based on your data, how are elements arranged into chemical families? 5. Infer: Look at your periodic table. How many valence electrons would you find for elements in each family? Boron family: Carbon family: Neon family: 6. Think and discuss: How do you think the number of valence electrons relates to an element's chemical properties? Reproduction for educational use only.
