Presentation Transcript

  1. Warm-up 10/23/12 • Teacher the Teacher: What is your least favorite food? • Review: What is the independent variable?

  2. The Periodic Table Where elements come together

  3. 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.

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

  5. 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

  6. Atoms: by the NUMBERS the element song

  7. Warm-up 10/24/12 • Teach the Teacher: If you had to be a teacher what subject would you want to teach? What subject do you think would be the hardest to teach? • Review: Is CO2 a compound or element, or mixture?

  14. Warm-up 10/25/12 • Teach the Teacher: What is the best outdoor winter activity? • Review: What is the group that you do nothing too?

  15. Flash Card On the Front Write: On the Back Write: Top number, tells the number of protons and electrons • Atomic Number

  16. 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

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

  18. 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.

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

  20. 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.

  21. Solid, Liquid, or Gas?

  22. Electron Shells • 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 is added each time. • The outer electron shell must be full (usually with 8 e-) to be stable.

  23. Warm-Up 10/26/12 • Teach the teacher questions: If you could get a gift card to any store in the mall, what store would it be? • Review: List as many elements as you can think of (you can use resources).

  24. 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.

  25. 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–
