Objective Periodic Table

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

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.
