2. Play until you discover what affects the charge of your atom or ion. What is a rule for making... A. A atom neutral (one with 0 extra charge)? ______________________________________________________________________________ B. A + ion (positive ion, one with extra positive charge)? ______________________________________________________________________________ C. A - ion (negative ion, one with extra negative charge)? ______________________________________________________________________________ 3. Show a neutral atom, a positive ion, and a negative ion. (These examples should be consistent with the rules you discovered.) All of your examples should also have a stable nucleus . Number of Particles? Draw Your Atom or Ion What is the Charge?
