Science 9 Chemistry Unit Big idea:
​The electron arrangement of atoms impacts their chemical nature.
          The periodic table groups elements according to their atomic number and properties (e.g., atomic                     size, metals/non-metals/semi-metals, chemical families, diatomic elements). 

           The arrangement of electrons determines the compounds formed by elements
