Your test will cover the following items: 1. All of the particles of an atom and their charges: protons +, neutrons 0, electrons - 2. You are to know that the Atomic Number = the number of protons of that element. The Atomic Mass = the number of protons and neutrons in the nucleus. 3. To find the number of neutrons you take the Mass Number - the Atomic Number = neutrons. 4. Protons can never change and still be that same element. 5. If the protons and neutrons are a different number then you have an isotope. 6. If the protons and electrons are a different number then you have a charged ion. 7. Make sure you know how to create a diagram of the elements 1-20 on the periodic table.
