3. Draw and Complete this Triple Venn Diagram For the three different types of subatomic particles LEFT SIDE

4. DOL’s Yesterday We did pretty good with atomic mass (AMU)
Had trouble with mass and electrons.
Had trouble with charge

5. DRAW THIS ON A RIGHT PAGE
MASS
CHARGE
PROTONS NEUTRONS
ELECTRONS DON’T MATTER FOR MASS
ONLY PROTONS AND ELECTRONS MATTER
More Protons = Positive Charge
More Electrons = Negative Charge

8. INVESTIGATE
Given the following three models, what can we tell about the electrons in the different electron clouds.

9. DOL Find the Atomic Mass Protons – 14 Electrons – 15 Neutrons - 15
2) What is the atomic mass if I add three electrons?
