The Atoms Family The Atoms Family was created by Kathleen Crawford, 1994 Presentation developed by Tracy Trimpe, 2006, http://sciencespot.net/

The Atoms Family Story Name: Patty Proton Description: Positive Favorite Activity: Hanging out at the Nucleus Arcade In the center of Matterville, there is a place called the Nucleus Arcade, where two members of the Atoms Family like to hang out. 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.

Her family is very apathetic and neutral about everything. 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. Name: Nelda Neutron Description: Neutral Favorite Activity: Hanging out at the Nucleus Arcade

Where do Perky Patty Proton and Nerdy Nelda Neutron hang out at? Nucleus Arcade WHERE ARE PROTONS AND NEUTRONS FOUND? So…Protons (+) and Neutrons (-) are found in the nucleus and are both quite large. This gives an atom its mass!!!!!!! They are called nucleons because they hang out in the nucleus of an atom

Protons (and tells you what element an atom is) The Atoms Family Atomic Number Symbol Name Atomic Mass Protons (and tells you what element an atom is) Atomic number equals the number of ____________ protons neutrons Atomic mass equals the number of ______________ + _______________.

Complete Worksheet

Start

Around the Nucleus Arcade, you will find a series of roadways that are used by another member of the Atoms Family, Enraged Elliott Electron. Elliott races madly around the Arcade on his bright red chrome-plated Harley-Davidson. He rides so fast that no one can be sure where he is at any time.

Elliott is much smaller than Patty and Nelda and he is always angry because these bigger relatives will not let him in the Arcade. He has a frown on his face, eyes that are squinted with anger, and a very negative (-) attitude. Name: Elliott Electron Description: Negative Favorite Activity: Racing around the arcade

So where does Enraged Elliott Electron hang our at? Nucleus Arcade WHERE ARE ELECTRONS FOUND? Electrons are found outside of the nucleus and are very small and negative

Atoms are made up of protons, neutrons, and electrons

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 18 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

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 was kidnapped?

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

Important Atoms are neutral meaning that the number of protons (+) in the nucleus = the number of electrons (-) outside the nucleus

Lets Practice drawing our protons and electrons with what we just learned Example: Draw an atom with showing its p+ and and e- if it has 8+ 6- 2- 8+ Notice the 8+ protons go in the middle and the 8- go around the nucleus, only two can go in the first energy level with the remaining six in the second energy level.

Draw and atom showing its p+ and e- if it has 5 p+ Lets Practice drawing our protons and electrons with what we just learned Draw and atom showing its p+ and e- if it has 5 p+ Draw and atom showing its p+ and e- if it has 12 p+ Draw and atom showing its p+ and e- if it has 7 e- Draw and atom showing its p+ and e- if it has 16 e- 8 8 2 Remember e- fill up 2, 8 , 8 from the nucleus
