Siven an element's atomic number and mass number, how can you tell the number of protons and neutrons in its nucleus?
jumber of protons = atomic number; number of neutrons = mass number - atomic number
number of protons = atomic number; number of neutrons = mass number + atomic number
number of protons = mass number; number of neutrons = atomic number - mass number

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
