TOPICS & OBJECTIVES

1010 - Law of Periodicity
    1010 - Convert between the name and symbol of the first 18 elements.
    1020 - Explain why the periodic table is organized in periods (rows).
    1030 - Identify periods and families (or groups) in the periodic table.
    1040 - Know the family name of groups 1A, 2A, 7A, and 8A.
    1050 - Identify metals, metalloids, and non-metals on the periodic table.
    1070 - Identify elements as representative, transition, or inner transition elements.
    1080 - Predict properties of an element based on it.
    1100 - Recognize common properties that distinguish between metals and non-metals.
    1110 - Predict the most common charge of an ion from its place in the Periodic Table.
 
1020 - Parts of the Atom
    1010 - Name the three basic sub atomic particles and differentiate them by charge and mass.
    1020 - Describe why Michael Farady named the particles he discovered ions, cations, and anions.
    1030 - Explain the existence of ions using the Plum-Pudding model.
    1040 - Explain how an AMU is defined.
    1050 - Describe the physical significance of atomic number and mass number.
    1060 - Write and interpret isotopic notation of different atoms, isotopes, and ions.
 
1030 - Atomic Mass
    1010 - Explain the difference between the mass of a particle and the average atomic mass of an element.
    1020 - Relate the average atomic mass of an element to an elements natural abundance and atomic mass of its isotopes.
    1030 - Provide Avogadros number to four significant figures (6.022 x10^23).
    1040 - Determine the atomic mass and molar mass of an atom of any element using a periodic table.
    1050 - Convert between a count of single atoms and mass in AMUs, using atomic mass.
    1060 - Convert begtween a count of moles of atoms and mass in grams, using molar mass.
    1070 - Relate the number of singles to the number of moles of a collection of any object.
