CP Objectives For Periodic Table

• 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](3.1).

• Describe the Modern Periodic Law

• Define Isoelectronic species and determine them for an element or ion.(Not responsible for in 20014-2015)

• Relate the position of an element on the Periodic Table to its Electron Configuration.[3.2](3.3).

• Relate the chemical charateristics (reactivity) to the Family elements and how Electron configuration detemines it.(3.3)

• Give appropriate Elements for the Groups, Periods, and other designated elements including metals, non-metals, and metalloids (semi-metals). [3.2](3.1,3.2).

• 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](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](3.4).

• Define Higher Ionization Energies (IE) and explain how they can explain the charge on the element's ion. (i.e. Al³⁺) [3.4] (Not responsible for in 20014-2015)

• 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](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](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
• 3 different methods of determining atomic radii (Covalent atomic radius, van der Waals radius and atomic radius in metals). Only need to know the word, don't need to know what they mean.
• Isoelectronic species (Not for 2014-2015)
• Shielding Effect (Not for 2014-2015)
• Malleable and ductile and deformability (Not for 2014-2015)

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.
