Objectives of Electron Configuration and Atomic Mass (Revised 2008 and 2015)

Essential Questions (EQ2): Are there any basic particles?

The student should be able to:(bolded number are MA Framework Standard numbers)

1. Explain the Charge Cloud Model of the atom and how it relates to the electron. Also, give the big picture of where the electrons are "located" and why it is so important that we know where the electrons are.

2. Explain the difference between classical (Newtonian) mechanics and quantum mechanics.[2.1,2.4]

3. Explain the contribution of Bohr, Planck and deBroglie to Quantum Mechanics. [2.1,2.4,2.5]

4. Explain Heisenberg Uncertainty Principle with respect to the electron.

5. Explain how Schrodinger's equation helped in understanding the location (highest probability of finding) of the electron and the establishment of subenergy levels and orbtials.

6. Define what a node is, what it means with respect to standing wave and the number of nodes in an energy level.

7. Generate the subenergy from lowest energy (closest to the nucleus) to the highest subenergy level (farthest from nucleus).Should be able to do this just from the Periodic Table.

8. Know the 3 rules of filling in electron in subenergy / orbital including name and what it means (Aufbau Principle, Hund'sRule, and Pauli Exclusion Principle)

9. Understand that only Hydrogen atom has degenerate subenergy levels and orbitals.[2.5]

10. Determine the correct electron configuration for any atom (Remember to write the last subenergy levels out as orbitals) including the half-half and half-full exceptions. Should be able to do this with just the Periodic Table.[2.7](2.4)

11. Be able to determine the number of valence electrons for any "s" or "p" block element.
---2017-2018 Students DO NOT DO

12. Define isotope and write (and explain) the symbolic representation of isotope.

13. Define atomic number and find it on a Periodic Table.

14. Define Mass Number and be able to calculate the correct number of each subatomic particle of an isotope knowing the Atomic Number and Mass Number.

15. Define atomic mass and be able to calculate atomic mass using Exact method.
