All about atoms

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

Racing around the arcade The Atoms Family Story Name: Patty Proton Description: Positive Favorite Activity: Hanging out at the Nucleus Arcade Name: Elliott Electron Description: Negative Favorite Activity: Racing around the arcade Name: Nelda Neutron Description: Neutral Favorite Activity: Hanging out at the Nucleus Arcade

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

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?

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

Decoding Atom Information carbon 6 12.0 Atomic Number # of protons Atom’s symbol Atom’s name Atomic mass

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

The Atoms Family - Atomic Math Challenge Atomic Number Symbol Name Atomic Mass A. P. E. M. - A.# = N protons electrons Atomic number equals the number of ____________ or ________________. protons neutrons Atomic mass equals the number of ______________ + _______________.

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

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

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

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