3D Models of Atomic Trends: Radius, Ionization Energy, and Electronegativity

This project involves creating a 3-dimensional model to visually represent trends in atomic radius, ionization energy, or electronegativity using straws. Each group member plays a key role: measuring and marking lengths, cutting straws, gluing them to the periodic table, and labeling the elements. The final product will include an appropriately titled periodic table (e.g., "3D Representation of the Trend in Atomic Radius"). This hands-on activity enhances understanding of periodic trends through collaborative learning.

Presentation Transcript

  1. Please do not write on this document. Thank you. Atomic Radius Data • 3-Dimensional Representation of the Periodic Trends [25 min] • Using the data provided to your group, create a 3-dimensional model that represents the trend that you have been assigned using straws. • One person measure and marks lengths on the straws. Lengths of straws are given in the right-most column of the table provided. • One person cuts the straws to the appropriate lengths. • One person glues the straws to the appropriate element in the periodic table. • One person labels the elements (writing on the straws or the periodic table). • Label the periodic table with an appropriate title (e.g. “3D Representation of the Trend in Atomic Radius”)
