Review warm-up
State the purpose
II. The Lesson:
Activity #1: Collect the Flame Test Lab Report
Activity #2: Review the location of the final electron for various elements using the periodic table 1. Identify the number of columns in the s, p, d, and f regions
2. Identify the row position, region, and column position of the element
3. List the location of the last electron [{row} s{column}; {row} p{column}; {row -1} d{column}; {row - 2} f{column + 1}]
4. Review Practice Examples: Mg, Nb, Np, Y, Cf, Pr, Nd, Pa, Pm Activity #3: Complete Ring of Fire demonstration (Mg ignition by Na & water)
