1. Periodic Trends

2. Atomic Radius- The distance from the nucleus to the outer edge of the electron cloud

3. Atomic Radius

4. Why does this make sense?
more protons=more pull on electrons
more shells=more size

5. Ionic Radius- the size of an ion compared to its original size

6. What are ions?
Charged atoms based on the gain or loss of an electron or electrons
Negative ions-gain an electron
Anions
Positive ion-lose an electron
Cations
