The students should be able to:<br> <br> <u>Periodic Table</u><br> <br> 1) Explain the difference between Medeleev and Moseley's Periodic Table. <br> <br> 2) Explain the relationship of an element's position on the Periodic Table to its atomic number <br>. <br> 3) Describe the Modern Periodic Law <br> <br> 4) Relate the position of an element on the Periodic Table to its Electron Configuration (only need to know # of ve<sup>-</sup> and what subenergy level (s or p). <br> 5) Relate the chemical charateristics to the Family elements and how Electron configuration detemines it (only ve<sup>-</sup>) .<br> <br> 6) Student will need to memorize the seven diatomic element (chemical formula and chemical name) and their phase (i.e. solid, liquid or gas) at room temperature.<br> <br> 7) Using your colored Periodic Table in your Assessment folder, be able to locate the following on the Periodic Table *Period,Group,Alkali metal, Alkaline Earth metals, Transition Elements, Inner Transition Elements,Lanthanoid series, Actinoid series, Noble or Inert Gases, Halogen, Nitrogen Family, Oxygen Family, metals, non-metals, semi-metals or Metalloids, (s-,p-,d-,f-block elements), phase of elements @20degreeC. <br> <br> <u>Periodic Table Trends</u><br> <br> <br> 8) Describe what Coulombic force (both attractive & repelsion) and the two major factors that affect the strength of the Coulombic Force (charge on the nucleus & electron). <br> <br> 9) Give and explain the trends for Coulombic force (CF) as you go down a Group and across a Period.<br> <br> 10) Give (and define) and explain the trend for Atomic radii/size (AR) as you go down a Group and across a Period. <br> <br> 11) Define Ionization Energy (IE) and give the trends for IE as you go down a Group and across a Period. Be able to explain the trend using C.F.(not Shielding effect). <br> <br> 12) Define Electronegativity (EN) and state(including why using C.F.)the general trends as you go down a Group and across a Period. <br> <br> 13) State and explain why (using other trends)the trends for Metallic Characteristics as you go down a Group and across a Period. <br> <br> 14) Using your knowledge of Metallic bond, explain properties of a metal (good electrical & heat conductor and Mallable/ductile). <br> 15) Explain how the ionic radius compares to the atomic radius for Metals and then for Non-metals. 'DO NOT explain general trends across Period' but will need to explain Down a Group (same as Atomic radii). <br> <br> <br> <u>Mole Concept (can use Assessment folder on test)</u><br> <br> 16) Understand the Mole concept as a grouping method that allows chemists to mass out (Massing), count (number of base unit/particles) and/or to obtain the volume (for gases only @STP) of substance that one could not mass/count/volume individually.<br> <br> 17) Correctly set-up and calculate One Step Mole Calculation Problems (mass for elements) using the class rule and the sig fig rules.</br> <br> 18) Be able to explain what a chemical formula is, its different types and how it used in determining the molar mass of a substance.<br> Be able to use molar mass in One Step Mole Calculations for massing compounds.<br> <br>
