1. THE STRUCTURE OF THE ATOM

2. Atomic Number Atomic Mass Element Symbol Element Name

3. The protons live in the nucleus. Atomic # = # of protons The neutrons also live in the nucleus. Atomic mass - # of protons = # of neutrons The electrons live outside the nucleus. # of protons = # of electrons

5. USE THIS INFORMATION TO CREATE A MODEL FOR THE CARBON ATOM  atomic # = # of protons  atomic mass - # of protons = # of neutrons  # of protons = # of electrons

6. THINK OF EACH RING AS A HIGHWAY… ONLY SO MANY CAN FIT ON EACH ROAD

7. CHECK YOUR WORK!

8. SKETCH OUT THE ATOM  Draw a sketch of the carbon atom in your packet.  Be sure to label your protons like this  Be sure to label your neutrons like this  Be sure to label your electrons like this

9. LET’S REVIEW Before we get started, can you tell me  The number of protons?  The number of neutrons?  The number of electrons?

10. APE Atomic Number = # of protons # of electrons

11. Atomic Number Atomic Mass
