The First Unit of Chemistry is Atomic Theory

The following standards will be covered in this Unit:

• CHEM.A.2.1.1. - Atomic Theory And Models - Describe the evolution of atomic theory leading to the current model of the atom based on the works of Dalton, Thomson, Rutherford, and Bohr.
• CHEM.A.2.1.2. - Isotopes And Mass Number - Differentiate between the mass number of an isotope and the average atomic mass of an element.
• CHEM.A.2.2.1. - Electron Configuration - Predict the ground state electronic configuration and/or orbital diagram for a given atom or ion.
  
• CHEM.A.2.2.2. - Characteristics Of Atoms And Ions - Predict characteristics of an atom or an ion based on its location on the periodic table (e.g., number of valence electrons, potential types of bonds, reactivity).

Here are the workbook pages for this Unit.  We will be  covering sections 4.1, 4.2, 4.3, 5.2, 5.3, 6.2.
