Chapter 4 Draw a diagram of an Aluminum atom showing correct location and number of protons, neutrons, and electrons. Draw protons with a + sign, electrons with a ‐ sign, and neutrons with a 0.
Pick another element, and write down its atomic number & mass number, and # of protons, neutrons, and electrons. 8
Chapter 5 Draw the Periodic Table (only A groups). Color code metals, nonmetals & semiconductors. (Hint: start with semiconductors and then the rest will be easy!)
Label “groups” and “periods”
