Protons, Neutrons, and Electrons
Using the periodic table of elements, young chemists fill in a chart of isotopes to show the atomic number, mass, charge, number of protons, number of neutrons, and number of electrons. The chart is followed by 11 questions that reinforce the same concepts. Answers are provided along the bottom of the worksheet. You can white them out and use this as a quiz, or leave them there and assign this as practice.
