1. Nuclear Notation

2. Friday Sept 5 Objective: Determine the number of protons, neutrons, and electrons in any element Checkpoint: – What is the identity of an element that has 11 protons, 13 neutrons, and 10 electrons? – How many neutrons does an atom of silver (Ag) have? Use your periodic table. Homework: – Subatomic particles wksht and isotopes due Monday

3. Mass = 108 AMU 47 protons (47 AMU) Mass = protons mass + neutrons mass 108 AMU = 47 AMU + ? 61 neutrons

4. Nuclear Technology Nuclear weapons prevent the loss of life Radiation is bad for your health We should invest in nuclear energy Strongly Disagree Somewhat Disagree Somewhat Agree Strongly Agree

5. Requirements Must include at least 3 words (most creative group wins a prize). Must have 3 different kinds of models.

6. Atomic Structure Quiz Name: Class: 1.6. 2.7. 3.8. 4.9. 5.10. Do not write on quiz, but you can work your answers out on your own paper. You may use your periodic table.
