# Build An Atom

Learning Objectives for this activity include: 1. Draw models that show atoms or ions. 2. Use information about the number of protons, neutrons, and electrons to • Identify an element and its position on the periodic table • Draw models of atoms • Determine if the model is for a atom or an ion. 3. Predict how changing the number protons, neutrons, or electrons will change the element, the charge, and the mass of an atom or ion.
