Objectives:
8.D Understands the subatomic particles makeup of every atom including name, charge, location and relative mass of protons, neutrons and electrons
8.D.2 Be able to solve for name, Standard Atomic Notation, number of protons, neutrons and electrons for first 20 elements
8.2 Understands how elements are arranged in the periodic table, and how this arrangement shows repeating patterns among elements with similar properties (e.g. numbers of protons, neutrons, and electrons; relation between atomic number and atomic mass) [Describe and explain the Periodic Table as a method of classifying elements and its use in predicting properties of elements]
Lesson:
(1) move today's formative quiz to next class. (2) practice Rutherford-Bohr diagrams. (3) discuss trend in periodic table (first column has one valence e-, second column has 2 valance e-, last column has full outer shell, second to last column is one e- short of full; nature tends toward stability.
Assignment:
(1) For vocab list, write Korean synonyms and definitions for ALL terms on list II. (2) Prepare for formative quiz.
