Atomic Theory & Periodic Table

Learning Targets Atomic
1. I can explain the progression of the atomic theory from the cannonball theory to the wave-mechanical (electron cloud) theory.
2. I can use Rutherford’s experiment to explain that an atom is made of mostly empty space and had a dense positively charged nucleus.
3. I can identify the three subatomic particles and differentiate between their locations, masses and charges.
4. I can draw Bohr models for elements in the ground state.
5. I can use the atomic number to identify the number of protons in the nucleus.
6. I can use the mass number and atomic number to determine the number of neutrons and explain what isotopes are.
7. I can calculate the average atomic mass of an atom using its naturally occurring isotopes and their natural abundances.
8. I can compare the energy of electrons based on which shell they are in knowing that as the shell number increases so does the energy level.
9. I can differentiate between electron configurations of an atom for the ground state and the excited state.
10. I can explain the Bright Line Spectrum as the energy released as electrons return to the ground state from the excited state.
11. I can identify elements based on their bright line spectrum which is unique. 


Learning Targets Periodic Table
  1. I can explain how Mendeleev set up his Periodic Table and compare it to how Mosely set up the Modern Periodic Table.
  2. I can classify elements as metals, metalloids or nonmetals.
  3. I can recall properties of metals, metalloids and nonmetals.
  4. I can identify periods and groups on the periodic table and use location to determine shells and valence electrons an element has.
  5. I can compare elements by their chemical properties based on the group that they are in on the periodic table.
  6. I can name specific groups on the periodic table and explain how those elements behave.
  7. I can compare trends on the periodic table such as atomic radius, ionization energy and electronegativity using Table S.
  8. I can define ionization energy and electronegativity.
  9. I can predict which elements will be reactive and those that will not.
  10. I can identify an allotrope as an element that exists in the same phase but in two or more forms such as O2 and O3.
