Pre / Post Assessment
8.1P.1
Describe the atomic model and explain how the types and
arrangements of atoms determine the physical and chemical
properties of elements and compounds.
Section A: Gathering Knowledge
1) Identify 3 chemical properties and 3 physical properties.
2) Diagram the atomic model. Label each part and identify the charges and locations of the 3 primary sub-atomic
particles.
3) Diagram and describe the arrangement of the atoms in a solid, liquid and a gas.
Section B: Processing Information
4) Compare and Contrast Protons, Neutrons, and Electrons. (Please provide at least 2 similarities and 2
differences.)
5) Distinguish between the physical properties of metals and non-metals.
Section C: Applying Knowledge
6) Using the periodic table entry to the right; evaluate the
entry and please list the number of Protons, Neutrons
and Electrons found in the element. Describe how to find
the number of neutrons.
