  1. Bellwork: Wednesday 2/22/2012 1- Turn in Pink Bellwork and get a NEW BLUE Bellwork! 2- Complete the table without looking at a periodic table. 8 8 O 14 14 13 27 Fe 26 30 26 20 20 Calcium

  2. Quiz Results • Not exactly what I would call ‘good’ • No retakes, redo’s, or corrections • BUT…. • Is there anything YOU could have done as a student to help prepare you for the quiz? • Is there anything I could have done as a teacher to help prepare you for the quiz? • Turn in Packet 9. I will be recording grades and passing them back.

  3. The Periodic Table of Elements CYOPT- Create Your Own Periodic Table… …as well as labeling and taking notes on each group of elements

  4. CYOPT- Structure of the Atom Valence Electron Negatively Charged Outside the Nucleus; in the outside shell Electron Negatively Charged Outside the Nucleus Charge of atom: Neutral Charge of nucleus: Positive Proton Positively Charged Inside the Nucleus Neutron Neutrally Charged Inside the Nucleus

  5. Reading the Periodic Table of the Elements • Each square of the Periodic Table usually includes the element’s name, atomic number, chemical symbol, and atomic mass.

  6. Reading the Periodic Table of the Elements Element’s Name Chemical (Atomic) Symbol NOTE: They can be organized different ways. What is an easy way to tell the difference between the atomic mass and the atomic number?? Atomic Number Atomic Mass

  7. CYOPT- Reading the Periodic Table • Atomic Mass = # of protons + # of neutrons • Atomic Number = # of protons • Organized by increasing atomic number • Valence Electrons • [Sketch Table] • An element’s properties can be predicted from its location in the periodic table • Group/Family = column (up/down) • # of valence electrons • Period = row (left to right) • # of orbitals/shells

  8. Create-Your-Own (CYO) Periodic Table (PT) • Fill in the Key at the top for Carbon • Follow my example on the board • Begin filling in the atomic symbol, atomic mass, and atomic number for the elements in BIG white PT—be sure to use the same order as the key! • If you didn’t finish the Life Science Vocab in CRT Packet, then it is homework! If you need a book to take home, you may check one out after school. Periodic Table Crossword Puzzles • Packet 9, Page 18 and 19 • Do your best from what you know, and use the periodic table and process of elimination to figure out the rest! • Oh….and it’s extra credit!

  10. Bellwork: Thursday 2/23/2012 Complete the table without looking at a periodic table. Na 11 11 23 Copper 64 29 12 12 12 Magnesium Gold 118 79 79 Ag 47 47 108

  11. CYOPT – Write in the “Metals” Section Metals • Almost 75% of all elements are classified as metals • Physical properties of metals: • hardness • luster (shininess) • malleability (can be pounded or rolled into shapes or flat sheets) • ductility (can be pulled out or drawn into wires) • Conductors (transmit heat and electricity easily) • Magnetic (attracted to magnets) • ex. iron (Fe), cobalt (Co), and nickel (Ni) • Most metals are solids at room temperature (high melting point) • Exception: Mercury (Hg)--liquid at room temperature

  12. Group 1: Alkali Metals 1

  13. Group 1: Alkali Metals • Causes skin burns if you come into contact with it • Physical Properties: • Soft- can be cut with a plastic knife • Shiny • Lightweight • Good conductors of electricity and heat • Low melting points • Tarnishes rapidly • Group 1 • 1 valence electron • which it readily loses to become a cation • Extremely reactive – NEVER found alone in nature • Only found in compounds, combined with other elements • Reacts violently with water to produce explosions

  14. BellWOrk Friday: 2/24/12

  15. Group 2: Alkaline Earth Metals 2

  16. Group 2: Alkaline Earth Metals • Physical Properties: • Fairly hard • bright white • good conductors of electricity • high melting points • high densities • Why called Alkaline? When mixed in solutions =pH greater than 7 • Those pH levels are defined as 'basic' or 'alkaline' solutions • Group 2 • 2 valence electrons • 2nd most reactive group of elements in the periodic table • Chemically bond very easily by giving away 2 electrons

  17. Groups 3-12: Transition Metals 3 4 5 6 7 8 9 10 11 12

  18. Groups 3-12: Transition Metals • Physical Properties: • Most are hard and shiny • All are good conductors of heat & electricity • Are fairly stable, reacting slowly or not at all with air and water • Most have very high melting and boiling points • Most dissolve in acids (except Gold!) • Most have luster • Groups 3-12 • Largest group of elements • Most commonly found elements • Follows NO rules when finding valence electrons • Use the two outermost shells/orbitals to bond with other elements • Most elements only use the valence shell

  19. Element review time!

  20. Element review time!

  21. Rare Earth Metals Lanthanides Actinides

  22. Rare Earth Metals: Lanthanides • Top row (Rare Earth Metals) • Fits in period 6 • Named after the first element in the row (Lanthanum) • Physical Properties: • Soft • Malleable • Shiny/high luster • High conductivity • Found naturally on Earth • Only 1 element in the series is radioactive

  23. Rare Earth Metals: Actinides • Some not found in nature • Only thorium and uranium exist on Earth in significant amounts • All the elements after uranium were created artificially in the lab • Bottom row (Rare Earth Metals) • Fits in period 7 • Named after the first element in the row (Actinium) • All are radioactive • Nucleus is very unstable • last for only a fraction of a second after they are made

  24. Other Metals (Metals in Mixed Groups) 13 14 15

  25. Other Metals (Metals in Mixed Groups) • Possess many of the same qualities as the Transition Metals • Located in groups 13, 14, 15 • Includes 7 Elements – Al, Ga, In, Sn, Tl, Pb, Bi • Follow “rules” when finding valence electrons • Physical Properties: • Solid & Opaque • Ductile & Malleable • High densities

  26. Metalloids 13 14 15 16

  27. Metalloids • Possess properties of both metals and non-metals • Semi-conductors • Found along the “stair-step” or “ladder” (between metals & non-metals) • Physical Properties: • Solids • Shiny or dull • Will conduct heat and electricity (but not as well as metals) • Metalloids: • Boron • Silicon • Germanium • Arsenic • Antimony • Tellurium • Polonium

  28. Group 17: Halogens 17

  29. Halogens- Group 17 • Group 17 • 7 valence electrons • 1 away from a full shell • Very close to being happy • Combine with many different elements • Often bond with elements from Group One • “Very reactive! – Only need 1 more electron to fulfill the “Octet Rule” • Never found alone in nature • All are poisonous non-metals

  30. Group 18: Noble Gases 18

  31. Noble Gases- Group 18 • Group 18 • Full valence shell • Hydrogen & Helium: full with 2 electrons • Others: full with 8 electrons • Happiest elements of all  • Will never combine with other elements (too stable) • Colorless, tasteless, & odorless gases • When electricity passes through them, they glow different colors

  32. Non-Metals 1 18 14 15 16 17

  33. Nonmetals • 17 nonmetals • Found to the right of the “stair step” on the periodic table & Hydrogen • Lack most of the properties of metals • Physical Properties: (most) • Dull • Solid nonmetals are brittle (not malleable/ductile) • Poor conductors of heat & electricity • Chemical Properties: (most) • Form compounds easily • EXCEPT Group 18 (Noble Gases)

  34. Create-Your-Own (CYO) Periodic Table • Man Made: :) Radioactive:  • Coloring: Letters: Black (s), Red (g), Blue (l) • Coloring: Outline each in a different color—see my example for help!!
