Students visit twelve stations and a diagram of an atom to find the number of protons, neutrons, electrons, atomic number, mass number, charge, and element of that particular atom.
I use this lab to reinforce parts of the atom, atomic number and mass number. The students are up and moving and aren't just sitting and completing a worksheet.
I have included two versions of the student worksheet- one which includes a column for the family of the periodic table and one which does not.
A key is included.
