1. Atomic structure

2. Anion (Negative ion) IONIZATION ENERGY Cation (Positive ion)

3. Electric current

4. ELECTRIC CIRCUITS SERIES: PARALLEL: Req = R1 + R2 + R3

5. Electrolysis Na+  cathode Cl-  anode
Ions: Touch electrodes  give up their charges to the electrodes  become neutral molecules  liberate (gas) OR deposit (solid)

6. ELECTROPLATING

7. Electric current and magnetism

8. Domains Magnetic material with domains misaligned
Aligned domains makes material highly magnetic
