Bellwork Read the article on page 58 in your text. Answers questions #1 and #2. Element 114 (short video) Counting protons, neutrons, and electrons Lewis Dot Diagrams Use your knowledge of energy levels to predict the number of valence electrons and construct dot diagrams. TEST CHAPTER 2: Thursday, September 13, 2012
Bellwork (turn in today) Read the article in your text on page 73. Answer questions # 1 and # 2. Emission Spectrum We will look at the chemistry of fireworks as we finish our discussion of emission spectra. Use the periodic table to determine the number of protons, neutrons, and electrons.
Bellwork Describe what is happening in the bio-luminescence of fireflies. (Use the terms electron, ground state, excited state in your answer.) The Atom 1. Be sure that your conclusion from the Emission Spectrum is complete.
2. Finish the Anticipation Guide handout today and turn in for daily assignment points. 3. Begin discussion on counting protons, neutrons, and electrons. Bellwork Describe the particles that make up an atom. (include charge, location, and relative mass) The Atom Emission Spectrum
*What is the ground state for an electron? *What is the excited state for an electron? *How does an electron move from the ground state to the excited state? *What happens when an electron returns to the ground state? *Using the website information below, identify the element that is show to you in class. (complete this on the back of the assignment handed out in class) LINK Spectrum by element Color Spectrum images Bellwork What did the ancient Greeks think were the fundamental elements? How does that differ from what we know today about the elements? History of the Atom Important people/ideas in the development of Atomic Theory
