<center><b>Periodic Table</b></center><br> <br> <i><b>Essential Question: Do you believe that? (theory explains observations)</b></i> <i>Each student will be able to:</i><br> *Explain the difference between Medeleev and Moseley's Periodic Table. <b>[http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_113.html 3.1]</b> *Explain the relationship of an element's position on the Periodic Table to its atomic number (i.e. Periodic law)<b>[http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_113.html 3.1](3.1)</b>. *Describe the Modern Periodic Law *Define Isoelectronic species and determine them for an element or ion. *Relate the position of an element on the Periodic Table to its Electron Configuration.<b>[http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_113.html 3.2](3.3)</b>. *Relate the chemical charateristics (reactivity) to the Family elements and how Electron configuration detemines it.<b>(3.3)</b> *Give appropriate Elements for the Groups, Periods, and other designated elements including metals, non-metals, and metalloids (semi-metals). <b>[http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_113.html 3.2](3.1,3.2)</b>. *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). *Define covalent atomic radius, van der Waals radius, and atomic radius in metals. State and explain why (using Coulombic force, C.F.) how the atomic radii changes as you go down a Group and across a Period. <b>[http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_113.html 3.4](3.4)</b>. *Define 1st 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). Also, state the two Exceptions for Period 2 & 3 (2 for each period). <b>[http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_113.html 3.4](3.4)</b>. *Define Higher Ionization Energies (IE) and explain how they can explain the charge on the element's ion. (i.e. Al<sup>3+</sup>) <b>[http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_113.html 3.4]</b> *Define Electronegativity (EN) and state(including why using C.F.)the general trends as you go down a Group and across a Period. <b>[http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_113.html 3.4](3.4)</b> *Explain how the ionic radius compares to the atomic radius for Metals and then for Non-metals. 'DO NOT usually explain general trends across Period'. Down a Group is same as Atomic radii. <b>[http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_113.html 3.4](3.4)</b> *State the difference between Metals and Non-metals for the characteristics of IE,EN,Luster, Deformability,heat/electrical conductivity, charge, and phase (at room temp). <b>[http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_113.html 3.4]</b>. *State and explain why (using other trends)the trends for Metallic Characteristics as you go down a Group and across a Period. <b>[http://www.doe.mass.edu/frameworks/scitech/2001/standards/chem10_113.html 3.4]</b>. Students need to be able to define (most are also stated above): *Modern Periodic Law *Electronegativity *Period / Row *Group / Family / Column *Coulombic Force *Ionization Energy (IE) *Higher IE *Covalent atomic radius *van der Waals radius *Atomic radius in metals *Isoelectronic species *Shielding Effect *Malleable and ductile and deformability Students need to 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.
