Isotopes

Isotopes

 7.   The organization of the periodic table is based on the properties of the elements and reflects the structure of atoms. As a basis for understanding this concept:​
  • b.   Students know each element has a specific number of protons in the nucleus (the atomic number) and each isotope of the element has a different but specific number of neutrons in the nucleus.
