4. The first energy street can only hold only two Electron brothers
The first energy street can only hold only two Electron brothers. The second energy street, called the Energy Freeway, can hold 8 brothers. The third energy street, called the Energy Superhighway, can hold 8 of the brothers.
Matterville
Energy Superhighway Can hold 8 electrons
Energy Freeway Can hold 8 electrons
Nucleus Arcade Contains protons & neutrons
Energy Street Can hold 2 electrons

5. The morale of Matterville is stable as long as each negative Electron brother is balanced out by one positive Proton sister. The number of residents in Matterville depends on the Proton and Neutron families.
Challenge: What would happen to the morale of Matterville if one Elliott Electron moved away to another atom town?

6. Challenge 2: What would happen to the morale of Matterville if one Elliott Electron moved to Matterville?

7. Decoding Atom Information

8. Decoding Atom Information cont:
# of protons = # of electrons 6 C
carbon
Atomic mass = # of protons plus the # of neutrons
12.0

11. Assignment: Finish the rest of the worksheet and turn in.

12. Outer Area (structure) of an Atom
Electron cloud (ring) - an area encircling the nucleus where electrons are likely to be found
The cloud contains energy levels
electrons are negatively charged particles located in specific energy levels
energy levels completely surround the nucleus
there is a specific order for the electrons to fill the energy levels

13. Outer Structure of an Atom
valence electrons are in the outermost energy level and are the electrons involved in reactivity or bonding
Valence electrons show reactivity
valence is the number of bonds an
atom can form
an atom is most stable when its outermost energy level is full

14. Outer Structure of an Atom
Energy levels completely surround the nucleus
Maximum of 2 electrons
Nucleus
Maximum of 8 electrons
