'''Periodic Table Chapter''' Students should be able to: *Explain the difference between Medeleev and Moseley's Periodic Table. ('''3.1''') *Explain the relationship of an element's position on the Periodic Table to its atomic number (i.e. Periodic law)('''3.1'''). *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.('''3.2'''). *Relate the chemical charateristics to the Family elements and how Electron configuration detemines it. *Give appropriate Elements for the Groups, Periods, and other designated elements including metals, non-metals, and metalloids (semi-metals). ('''3.2'''). *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. ('''3.4'''). *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). ('''3.4'''). *Define Higher Ionization Energies (IE) and explain how they can explain the charge on the element's ion. (i.e. Al+3) ('''3.4''') *Define Electronegativity (EN) and state(including why using C.F.)the general trends as you go down a Group and across a Period. ('''3.4''') *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. ('''3.4''') *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). ('''3.4'''). *State and explain why (using other trends)the trends for Metallic Characteristics as you go down a Group and across a Period. ('''3.4'''). 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.
