- C4: Chemical Patterns
- Periodic Table
- Interpreting
- RAM (Relative Atomic Mass)
- Proton Number
- Across the Table = Periods
- Up and down the table = Groups
- Atomic Structure
- Protons
- Neutrons (No charge)
- Electrons
- Interpreting
- Ionic Bonding
- when a element gains a an electron it is positively charged where as the element that has gained a electron is negatively charged
- Group 7
- Re activity
- Re activity decreases. electricity bond is weaker. (Opposite to Group 1)
- Re activity
- Group 1
- Reactivity
- If you go from Lithium to Sodium to Potassium the electricity bond gets weaker and weaker between the negative electrons and the positive protons.
- Re activity increases as you go down the group.
- If you go from Lithium to Sodium to Potassium the electricity bond gets weaker and weaker between the negative electrons and the positive protons.
- Reaction
- Oxygen
- Tarnishes in moist air
- Chlorine
- Colorless crystalline salt (when reacted with Group 1)
- Water
- Lithium = Fizzing
- Sodium = Violent fizzing
- Potassium = Flame
- Oxygen
- Reactivity
