b) Develop a relationship (in the form of a single sentence or math equation) that car the charge of an atom or ion. 6. Play with the simulation to discover what affects the mass number of your atom or ion a) What is a rule for determining the mass number of an atom or ion? Practice applying your understanding by playing 1" and 2d levels on the game screen.
