The students should be able to:

Periodic Table

1) Explain the difference between Medeleev and Moseley's Periodic Table.

2) Explain the relationship of an element's position on the Periodic Table to its atomic number
.
3) Describe the Modern Periodic Law

4) Relate the position of an element on the Periodic Table to its Electron Configuration (only need to know # of ve- and what subenergy level (s or p).
5) Relate the chemical charateristics to the Family elements and how Electron configuration detemines it (only ve-) .

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.

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.

Periodic Table Trends

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).

9) Give and explain the trends for Coulombic force (CF) as you go down a Group and across a Period.

10) Give (and define) and explain the trend for Atomic radii/size (AR) as you go down a Group and across a Period.

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).

12) Define Electronegativity (EN) and state(including why using C.F.)the general trends as you go down a Group and across a Period.

13) State and explain why (using other trends)the trends for Metallic Characteristics as you go down a Group and across a Period.

14) Using your knowledge of Metallic bond, explain properties of a metal (good electrical & heat conductor and Mallable/ductile).
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).

Mole Concept (can use Assessment folder on test)

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.

17) Correctly set-up and calculate One Step Mole Calculation Problems (mass for elements) using the class rule and the sig fig rules.

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.
Be able to use molar mass in One Step Mole Calculations for massing compounds.
