Objectives of Electron Configuration and Atomic Mass

Essential Question: Do you believe that? (theory explains observations)
Enduring Understanding: ?????

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

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

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

3. Explain Heisenberg Uncertianty Principle with respect to the electron.

4. 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.

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

6. Memorize the four Quantum numbers (Principle, Azimuthal,etc), the symbol and what they mean.

7. Memorize the Lyman series, Balmer series and Paschen series and how they related to energy level that the electron falls back down to and amount of energy (part of the electromagnetic spectrum) that the atom emits.[2.5]

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

9. 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.

10. 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)

11. Determine the correct electron configuration for any atom or ion(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)

12. Be able to determine if an element is a metal, non-metal or metalloid from location of Periodic Table and if the element will form a cation or anion. Be able to explain what a cation and anion is with respect to number of subatomic particles.

13. Be able to determine the number of valence electrons for any "s" or "p" block element.

14. Be able to explain what an anion and cation are, what type of element they come from, and generate the electron configuration for any ion (as long as you are given the charge of the ion).

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

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

17. 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.

18. Define atomic mass and be able to calculate atomic mass using Exact and Non-exact (Mass Number) method.
