Atomic Orbital Collection

thingiverse

This is a collection of atomic orbitals. The primary concept was derived from BlendeLabor's probability shapes. The files contain layouts for every s, p, d, and f orbital, as well as a connector that can be used to hold all three p orbitals together in place. These orbitals make excellent models for showing students the shape of atomic orbitals in 3D form. They can also be used to display geometry in bonding, especially when discussing pi and sigma bonds, using combined p orbitals. This project contains every orbital that I have created, all located in one place. The orbitals can be found as object files on Thingiverse as well. Print Settings Printer: Da Vinci Jr. Rafts: Yes Supports: No Infill: Hollow-5% Notes: Rafts should be used to help stabilize the orbitals while they print. Supports are not required. Printing the orbitals with 0 infill works fine. If you'd like, making them a bit more solid with 5% infill also works. A small amount of hot glue helps keep the orbital connections together. Standards NGSS CCSS Overview and Background Preparation: Students should already be familiar with the concept of probability densities. They should also understand that electrons behave like waves, so we cannot know their exact positions. The idea of what an orbital is should already have been introduced. Objectives: * Students will be able to describe the 3D shapes of atomic orbitals. * Students will be able to describe how various orbitals can line up in order to form single, double, and triple covalent bonds. Lesson Plan and Activity These models are designed to serve as manipulatives that help students grasp the 3D shapes of the atomic orbitals. They can be introduced in a variety of ways so there's no one specific activity they're designed for. I have often reached for them in class whenever referencing the orbitals, types of bonding, and relative reactivity of bonds. They have also been very useful in upper level chemistry classes when describing sigma and pi bonds, as well as hybridization. They can also be used in combination with my hybrid orbital models: http://www.thingiverse.com/thing:1239504 Materials Needed No additional materials needed except the models.
