Students will cut out atomic models of the first 18 elements on the periodic table paste them in the correct group and period. The atomic models only show the electrons. Students can count the number of valence electrons to figure out which group the atom belongs to. Students can count the number of energy levels to figure out which period the atom belongs to. The elements will only be in periods one through three and groups one and two and 13 through 18.
