6. The smallest piece of matter that still has the chemical and physical properties of that matter.

7. Democritus in 400 B.C.

8. All the matter in the universe

9. Protons particles with positive charges found in nucleus of atom Determines the type of atom

10. Neutrons - particles with no charge found in the nucleus of the atom # of neutrons can vary

11. Electrons – particles with negative charge Found around the outside of the atom Determine how atom will react with other atoms

13. The Atom Poster Draw what you think the atom looks like Drawing must include the atom and a color coded key. Include the correct number of protons, electrons, and neutrons. The Atom - BeforeThe Atom - After Draw Today

14. TOD: What was your drawing from yesterday missing?

15. Atoms

16. Look at the back of your notes from yesterday. Are all the pictures of atoms? How are they similar? How are they different?

17. Bohr Model

18. What is a Bohr Model? Shows all the protons, neutrons, and electrons contained within an atom. Protons and neutrons are drawn in the Nucleus. Electrons are drawn on ENERGY LEVELS or SHELLS or ELECTRON CLOUDS (the rings found around the nucleus).

19. Energy Levels Energy levels can only hold a certain amount of electrons. Energy LevelMaximum Number of Electrons 12 electrons 28 electrons 318 electrons 432 electrons 550 electrons

21. Practice Hydrogen

22. Practice Helium

23. Practice Magnesium

24. Finish the following alone: Sulfur Oxygen Copper Francium

25. How are electrons arranged in Atom? Complete for HOMEWORK! DUE TOMORROW FRIDAY

26. Bohr Model Quiz Energy LevelMaximum Number of Electrons 12 electrons 28 electrons 318 electrons

27. Question 1: Flourine Protons = 9 Electrons = 9 Neutrons = 5

28. Question 2: Magnesium Protons = 12 Electrons = 12 Neutrons = 12

29. More Practice Nitrogen

30. Calcium

31. Do and Answer Draw a Bohr Model for Oxygen Hydrogen (twice) Using the drawing try to draw a Water Molecule. Define: atom, compound, molecule

32. TOD Draw a Carbon Atom –6 protons –6 electrons –6 neutrons –Label the parts and the charges

33. In your notes: Make 3 circle maps for: Proto n Neutro n Electro n

34. Energy Levels vs. Shells

35. Preview to Calculating Protons, Electrons, and Neutrons Subatomic Particle Total Number found in Atom Protons Electrons Neutrons

36. Preview to Calculating Protons, Electrons, and Neutrons Subatomic Particle Total Number found in Atom Protons Electrons Neutrons

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

38. Unscramble these words: uceulns urntneo toonrp cneletro mota mocriusdet

40. How do the Structures of Atoms Differ? Atomic number Mass number Atomic mass

41. Atomic Number = the number of protons

42. Identify the type of atom, the number of protons and the number of electrons: Atomic number 16 43 4 6

43. Mass Number – the number of protons and neutrons Fluorine 9 protons + 10 neutrons = 19 Carbon 6 protons + 6 neutrons = 12

44. Atomic Mass (Weight) = the avg of the # of protons plus the # of neutrons for all the diff kinds of one type of atom Proton1.0053 amu Neutron1.0087 amu Electron0.000549 amu (ignore)

45. Name: Nelda Neutron Description: Neutral 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. 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. The Atoms Family Story Name: Patty Proton Description: Positive Favorite Activity: Hanging out at the Nucleus Arcade

46. Name: Elliott Electron Description: Negative Favorite Activity: Racing around the arcade 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.

47. 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. Nucleus Arcade Contains protons & neutrons Energy Freeway Can hold 8 electrons Energy Superhighway Can hold 18 electrons Energy Street Can hold 2 electrons

48. 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?

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