Unit 04 Arrangement of Electrons in Atoms

I understand that electrons arranged around the nucleus of an atom so that the atom can become more stable.

Target 04-01 Use Bohr's Model of the atom to explain how atoms give off different forms of electromagnetic energy and to explain how energy levels can be measured.

"I can" statements:

04-01 a.  Use the mathematical relationship among the speed, wavelength, and frequency of electromagnetic radiation.

04-01 b.  Discuss the significance of Einstein's photoelectric effect on the model of the atom.

04-01 c.  Describe the evidence supporting the dual wave-particle nature of light.

04-01 d.  Explain how the line-emission spectrum of hydrogen was used to develop Bohr's model of the atom.

04-01 e.  Use line-emission spectra to identify elements.


Target 04-02 Describe the location of an electron.

"I can" statements:

04-02 a.  Explain how the Heisenberg Uncertainty Principle and the Schrodinger Wave Equation led to the quantum model of the atom.

04-02 b.  List the total number of electrons needed to fully occupy each main energy level.

04-02 c.  Write the four quantum numbers for any electron.

04-02 d.  Write the orbital notation and electron configuration for any element in atomic and ionic form.

04-02 e.  Explain how the Aufbau principle, Pauli Exclusion Principle, and Hund's Rule apply to where an electron is located.



Target 00-01 I can write technically.  I can communicate in subject specific style.

Target 00-02 I can use symbols for ions and identify ions from their symbols.

Target 00-03 I can use the Periodic Table to predict qualities of elements.

Target 02-04 I can use dimensional analysis to solve chemistry problems.

Target 03-01 Describe how each of the parts of the atom was discovered and by whom.
