How do you make a 3-d iodine atom model?

Answer 1

To makea model of iodine you'll need lots of spheres the same size. Join them together in pairs to represent the iodine molecule I2. The bond you are making here is a covalent bond and won't break if your iodine becomes a gas. You need a whole collection of iodine molecules and sit them down together as close as you can get them to represent solid iodine. The forces holding them together are an example of van der Waals forces. These forces are strong enough to make iodine be a solid at room temperature.... but if you give them some energy by shaking your model, they should start to leap about as you solid iodine becomes a gas. This change is called sublimation.

Answer 2

To make a 3D iodine atom model, you can use small Styrofoam balls to represent the nucleus and electrons. Paint the nucleus ball dark purple or black to represent iodine's atomic number 53. Attach smaller white or light blue balls around the nucleus with toothpicks to represent the electrons in the outer shells, following the electron configuration of iodine. This will give you a basic 3D model of an iodine atom.
