  1. Entry Task: October 29th Monday Entry Task Question: What element has 4 valence electrons, a metalloid and has 3 energy levels? You have 5 minutes!

  2. Agenda: • Sign off on Alien periodic table • Discuss Alien periodic table- QUICKLY • Self Check on Periodic Table • HW: Ch. 6 section 3 reading notes

  3. Alien Element Clue What did you learn ? Bo, Wo, J, L They are noble gases Noble gases are in group 18 Bo, Wo, J, L Wo has greatest atomic mass, Bo the least The atomic mass of the elements increases as you move left to right and top to bottom on the Per. Table

  4. Bo L J Wo

  5. Alien Element Clue What did you learn ? Pf, El Pf is the lightest element, El is the heaviest The atomic mass (lightness or heaviness) increases as you move left to right and down the periodic table X, By, Ch, Q They are the most reactive group Reactivity decreases as you move from left to right on the Per. Table

  6. Pf Bo Ch L By J Q Wo X El

  7. Alien Element Clue What did you learn ? A, V, Kt Non-metals who typically gain or share one electron -Atoms can gain or lose electrons -The # of electrons an atom will gain, lose or share is determined by the group that it is in. E, Hi, T, Ss They are metalloids Metalloids are located between the metals and the non-metals along the zigzag line.

  8. Alien Element Clue What did you learn ? T T has more protons than Hi The number of protons is equal to the atomic #

  9. Pf Bo E Ch L Kt By Yz Hi A J T Q Ss V Wo X El

  10. Alien Element Clue What did you learn ? Kt and By Table salt is made of NaCl Kt and By make table salt D D has 4 protons The number of protons is equal to the atomic number on the periodic table

  11. Pf Bo E Ch D A L Kt By Yz Hi J T Q Ss V Wo X El

  12. Alien Element Clue What did you learn ? Fx Group 14 same period as A, R and Do Periods have the same energy levels R, Do R is less reactive than Do The further to the right you move on the periodic table, the less reactive the element is

  13. Pf Bo E Ch D Fx A L Kt By Yz Hi J Do R T Q Ss V Wo X El

  14. Alien Element Clue What did you learn ? Nu Is the lightest in Group 16 Same spot as oxygen An An has 49 electrons The number of electrons = the atomic number

  15. Alien Element Clue What did you learn ? Z, Pi Group 2 Atoms on the left side of the periodic table tend to lose electrons

  16. Alien Element Clue What did you learn ? M, G, Ss Group 15 G has less electrons than M As you move across the periodic table from left to right, the number of electrons increases in each period Up, Oz, Nu They all gain 2 electrons Elements on the right side of the periodic table gain electrons (except for the noble gases)

  17. Pf Bo E Nu Ch D Fx G A L M Kt By Z Yz Hi Oz J T Up Q Do R Ss V Wo X Pi El An

  18. 1. What group # are the halogens? GROUP 17 2. What is the name of the group 2? ALKALI EARTH METAL

  19. 3. What group # has the coinage elements- Silver, Gold and Copper) 11 4. How many valence electrons are in the alkali group? ONE

  20. 5. Why are groups “grouped” together? SAME # of VALENCE ELECTRONS Have the same properties. 6. What groups are the transitional elements? Groups 3-12

  21. 7. What 2 properties does the noble gas share? Gases, nonreactive, nonconductive • Explain why they have these properties? The valence orbit is filled with electron

  22. 9. What determines the chemical and physical properties of elements? The NUMBER of VALENCE ELECTRONS.

  23. 10. What element is in the period 5, group 7? Technetium- Tc 11. What element is in the period 6, group 2? Barium-Ba

  24. 12. Period refer to what part of an atom? # of orbits or energy levels 13. Groups refer to what part of the atom? # of valence electrons

  25. 14. What element is in the period 7, group 9? Meitnerium-Mt 15. What element is in the period 4, group 14? Germanium-Ge

  26. Provide the period and group for the following elements 4 2 5 11 Calcium p_____, g_____ Silver p _____,g_____ Radon p_____, g_____ Carbon p_____, g_____ Potassium p_____, g_____ Yttrium p_____, g_____ Aluminum p_____, g_____ Krypton p_____, g_____ 6 18 2 14 4 1 5 3 3 13 4 18

  27. Non metal 8 Unreactive, gas, stable, keeps ve 18 2 2 1 reactive, solid, shiny, loses ve metal 1 4 4 7 Gases noncoductive dull 17 6 6 nonmetal

  28. 5 4 Both metal and non metal properties 14 3 metalloid 3 Conductive, shiny, solid 5 5 metal ? 5 2 6 6 2 Conductive, shiny, solid, metal
