Mini Challenge

Building Atomic Models

In this activity, students will build three-dimensional models of atoms and ions using simple materials like Styrofoam balls and wires. Through this construction, they will be able to visualize and better understand electronic distribution and anomalous configurations.

Instructions

1. Divide the students into groups of 3 to 4 people.
2. Distribute the necessary materials: Styrofoam balls of different sizes to represent protons, neutrons, and electrons; wires or sticks to represent the electronic layers.
3. Each group should choose a specific element or ion to model, ensuring that some groups work with elements that have anomalous electronic distributions, such as copper.
4. Students must assemble the atomic nucleus with protons and neutrons and use the wires to create the electronic layers, distributing the electrons according to the correct electronic configuration.
5. Once completed, each group must present their model to the class, explaining the electronic distribution and highlighting any anomalous configuration.

Objective: Visualize electronic distribution and understand anomalous configurations through the construction of three-dimensional models, promoting practical and collaborative learning.

Duration: 30 - 35 minutes

Evaluation Exercises
