Atoms FamilyAtoms Family
In the center of Matterville, there is a place called the Nucleus Arcade, where two
members of the Atoms Family like to hangout. Perky Patty Proton, like her sisters, is quite large with a huge smile and eyes that
sparkle (+). Patty is always happy and has a very positive personality. Nerdy Nelda Neutron
is large like Patty, but she has a boring, flat mouth and eyes with zero expression (o). Her
family is very apathetic and neutral about everything. Patty, Nelda, and their sisters
spend all their time at the arcade.

Around the Nucleus Arcade, you will find a series of roadwaysthat are used by another member of the Atoms Family, Enraged
Elliott Electron. Elliott races madly around the Arcade on hisbright red chromeplated Harley-Davidson. He rides so fast that
no one can be sure where he is at any time. Elliott is muchsmaller than Patty and Nelda and he is always angry becausethese bigger relatives will not let him in the Arcade. He has a
frown on his face, eyes that are squinted with anger, and a verynegative (-) attitude. The first energy street can hold
only two Electron brothers. The second energy street, called theEnergy Freeway, can hold 8 brothers. The third energy street,called the Energy Superhighway, can hold 18 of the brothers.

The morale of Matterville is stable as long aseach negative Electron brother is balanced
out by one positive Proton sister. Thenumber of residents in Matterville depends
on the Proton and Neutron families.
Challenge: What would happen to the moraleof Matterville if one Elliott Electron was kidnapped?
