This chart reflects groups 1-2-14-15-16-17-18 no lanthanides or actinides. I do not teach the transition metals to 7th grade.
Procedure- Subtract the number of protons from the atomic mass and this tells you your number of neutrons. If the neutron number is the same as the proton number the atom is not an isotope.
Today's standards are vast. Inquiry wants us building and not spending months on one area. Touch on it each year and scaffold. By grade 8 you will have achieved mastery.
