  13. Warm-up 11/20/13 • Teach the Sub: What is the best part about Thanksgiving? • Sub Teaches Students: What is the hardest part about subbing? • Review: Is H2O a compound or an element?

  14. Chem Idol Round 3 • Round 2 Winner: Mr Parr-Inside Atoms • Round 3 Contestants: • Mendeleev Song • Mr. Edmonds-Groups and Periods • Oort Kuiper-Periodic Table Rap

  15. Warm-up 11/25/13 • Teach the Teacher: If you had to have a thanksgiving food eating contest what would you want to eat? • Review: What number tell you the number of protons and neutrons?

  16. Flash card • On one side: • How to find # of neutrons • On the other side: • Atomic Mass-atomic #= #of neutrons

  17. Warm-up 11/26/13 • Teach the Teacher: Would you rather go back in time and meet your ancestors, or go into the future and meet your grandchildren? • Review: What does the atomic # tell you?

  18. Flash Card On the Front Write: On the Back Write: Number of electrons in the outer most shell • Valence Electrons

  19. The Periodic Table Where elements come together

  20. The Periodic Table • Periodic Table—an organized list of all known elements that are arranged according to their properties. • The 1st person to organize elements was Dmitri Mendeleev in the 1800s. • Mendeleev organized the elements by their atomic mass and left spaces for unknown elements.

  21. The Modern Periodic Table • Mendeleev’s table was mostly correct, but it is more accurate to organize elements in order of increasing atomic number.

  22. Protons = Atomic Number • Atoms get their identity and properties due to the number of protons they have • change the #p+ change the element • Electrons = Number of protons • For neutral atoms,ionsare different • Neutrons = Atomic Mass – Atomic Number • Atoms of the same element can have different masses. These are calledisotopes. The difference in mass is due to more or less neutrons

  23. Warm-up 12/2/13 • Teach the Teacher: What did you do during the day/after eating thanksgiving (play games, watch football, play football, etc.) • Review: What is the smallest piece of matter?

  24. Flash Card On the Front Write: On the Back Write: Holds protons and neutrons • Nucleus

  25. Atoms: by the NUMBERS the element song

  26. Chemical Symbols (Scientist Texting) • Abbreviations for chemicals • Punctuation is KEY • Capital Letters big, little letters small • Spacing • Elements • ALWAYS Start with a capital letter • Symbols can be 1,2 or 3 letters • First letter is capitalized and 2nd & 3rd are lowercase

  27. Example of Messing up Chemical Symbol • CO doesn’t equal Co • CO = Carbon monoxide • Co = Cobalt

  28. Periods • Periods—horizontal rows of elements on the periodic table. • Periods are numbered 1-7 • Elements increase by one proton as you move from left to right across a period.

  29. Groups • Groups (or families)—vertical columns on the periodic table. • They are numbered 1-18. • Elements in each group have similar properties.

  30. Electrons & The Periodic Table • The periodic table organizes elements based on where their electrons are located. • Electrons (e-)—are located in different energy levels around the nucleus. • Elements in the same group have electrons arranged similarly which gives them similar properties.

  31. Solid, Liquid, or Gas?

  32. Electron Shells/Orbitals • The number of energy levels or electron shells is determined by the period number. • Period 1: 1 electron shell and can hold 2 e- • Period 2: 2 electron shells & can hold 8 e- • Period 3: 3 electron shells & can hold 16 e- • As you move down the periodic table, 1 electron shell/orbital is added each time. • The outer electron shell must be full (usually with 8 e-) to be stable.

  33. Warm-up 12/3/13 • Teach the Teacher: If you could teach, what grade level would you want to teach and what subject would you like to teach? • Review: How do you find the number of neutrons?

  34. Flash Card On the Front Write: On the Back Write: Elements found in the same row (period=sentence) • Periods

  35. Flash Card On the Front Write: On the Back Write: Elements in the same column, have similar properties Groups

  36. Electron Dot Diagrams • You can show the number of electrons in the outermost electron shell by using an electron dot diagram. • Dot diagrams use valence electrons which are the electrons in the outer electron shell. • Electron Dot Diagram—uses the symbol of the element and dots to represent the valence electrons.

  37. Bohr Model

  38. Ions • atom or molecule with missing or extra electrons • Ions are charged particles (positive or negative) • charge = #protons - #electrons • charge given as a trailing superscript • positive ions are cationsX+ • negative ions are anionsX–

  39. Warm-up 12/4/12 • Teach the Teacher: If you were a bird, what kind of bird would you be? (example: bald eagle, hummingbird, penguin) • Review: What is all the information that is given to you on one square of a periodic table?

  40. Flash Card • On one side: • Bohr Diagram • On the other side: • Shows total # of electrons on orbitals

  41. Flash Card • On one side: • Electron Dot Diagram • On the other side: • Shows the number of valence e-

  42. Warm-up 12/5/13 • Teach the teacher: What would be the most fun thing to do while baby-sitting an eight year old? • Review: Do groups go up and down or across the periodic table?

  43. Flash Card • On one side: • Ion • On the other side: • An atom with an extra or missing electron (#e ≠ atomic number)

  44. Flash Card • On one side: • Cation • On the other side: • An atom that is missing an electron (more protons)(cats are more + then onions)

  45. Warm-up 12/6/13 • Teach the Teacher: Any significant hospital visits? • Review: What number tells you protons and electrons?

  46. Warm-up 12/9/13 • Teach the Teacher: What’s the thing you’re most scared to do? What would it take to get you to do it? • Review: What are orbitals?

  47. Flash Card • On the front • Isotope • On the back: • Atoms of the same element that have a different # of neutrons

  48. Flash Card • Orbitals • Energy levels that hold electrons (e- shells) (2,8,8/16)
