Students were welcomed back and we began on the "Periodic Table & Periodic Law" Vocabulary (54 pt). They were instructed to complete them for homework.

Students continued to work on the 1st Sem. Exam Review Guide (50 pt)and were also given the 2nd Sem. Exam Review Guide to complete for their final grade of the 1st Semester. They were also given the requirements for their exam and dates for the exam also.

Students quickly reviewed the Electrons in Atoms Ch. Review and then took the Electrons in Atoms Chapter Test (100 pt).  We then made sure all students had the 1st Qtr Sem. Exam Review Guide and understood the purpose and grading of the 1st & 2nd Qtr Sem. Exam Review Guides

Students finalized the chapters information by talking about valence electrons and completed the Electron Dot Model WS (30 pt) for homework and Electrons in Atoms Crossword Puzzle (40 pt) in class.  They also completed the Electrons in Atoms Voc. Test (60 pt) today.

Students learned how to draw electron configurations using the following rules: Aufbau, Pauli Exclusion Principle, and Hund's rule.  We also learned the shorthand notation and orbital diagram notation.  They were assigned the Electron configuration Notation WS (56 pt) for homework.  We will cover valence electrons and complete the WS on Wednesday as well as have the Electrons in Atoms Voc. Test on Wednesday.  They will have the Electrons in Atoms Voc. Test on Thursday. They will have the Solid, Liquid and Gas Chapter Test on Thursday. Once again, they were reminded to pick up the 1st Sem. Exam Rev. Guide to prepare for the 1st Semester Exam next week.

Students continued the notes and discussion from the PowerPoint "Electrons in Atoms" as we covered the Quantum Theory of the Atom, orbital shapes, Pauli Exclusion Principle and Hunds Rule.  We completed class as students began the examples of Electron Configurations WS.  Students were reminded orally and on the board of the Electrons in Atoms Voc. Test on Wednesday and Chapter Test on Thursday.  They can pick up their 1st Sem. Exam Review Guide at any time during the week. 

Students learned about the photoelectric effect and how it benefits us today as we began to see light as a particle.  We learned about Einstein's contribution to the light theory and how atomic emission spectra help us identify energy.

Students went over how to read the Electromagnetic Spectrum and the properties of waves.  We went over amplitude, wavelength, speed, and frequency and how they determine wave properties.  They were assigned a Wave Speed Word Problem WS (30 pt) for homework.

Students began notes on "Electrons in Atoms" from the PowerPoint.  They were reminded to have a calculator for class tomorrow.  The objectives for the early part of the chapter were emphasized as well as the current structure of the atom and scientists who discovered the parts.  They were reminded to have all of the information from the 1st day in preparation for the 1st Semester Exam in 2 weeks.

Students took the "Atomic Structure" Chapter Test (100 pt) and began the "Electrons in Atoms" Vocabulary. (76 pt)
