Quantitative Lesson 20 "Electromagnetic Radiation"
Science and Technology Standards:
PA Standard 3.4.10A: Classify and describe, in equation form, types of chemical and nuclear reactions
Purpose:
1. I will identify the regions on the periodic table.
2. I will identify how wave properties of an electron relates to the electron cloud model.
3. I will identify the how electrons create light.
4. I will compare how light emission of similar energy levels differs for elements in the same row on the periodic table.
5. I will identify the properties of metals, nonmetals, and metalloids.
6. I will identify how the atomic size and ionization energy trends on the periodic table.
