8.1P.2
Explain how the Periodic Table is an organization of
elements based on their physical and chemical properties.
Section A: Gathering Knowledge
1) Identify the element located in period 4 and group 5. List the number of protons and electrons in this element.
2) Element 17 and Element 11 bond together very easily. Identify the type of bond formed between these two
elements, describe the process, and identify three other elements that would readily bond with element 17.
3) Describe the trend of reactivity within the alkali earth metals. Identify which of these elements are the most
reactive and least reactive.
Section B: Processing Information
4) Compare and contrast the physical and chemical properties of Metals, Non-Metals and Metalloids.
5) Distinguish between covalent bonds and ionic bonds, and describe how bonding allows atoms to make
compounds.
Section C: Applying Knowledge
6) Predict the placement of newly discovered elements on the periodic table. Justify your answer.
