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

Periodic Table Trends

1) 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).

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

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

4) 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).

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

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

7) 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

1) 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.

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

3) 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.
