With this worksheet, students relate the number of protons, electrons, and neutrons to an element's atomic mass and atomic number. Included in this purchase are four different versions of a similar worksheet. Two include either atomic number or chemical symbol, one include both atomic number and chemical symbol, and one is a blank table (with an example row) so that students can pick their own elements to fill in. All worksheets are included in both English and Spanish versions.
This is designed for students to use AFTER they have already learned the parts of an atom. Knowledge of how to calculate the number of protons, neutrons, and electrons from the atomic number and mass is recommended, but not necessary.
