Why does the Periodic Table of Elements work?

Use the Periodic Table to identify various elements and facts about them.

Reminders:  The columns on the Periodic Table are called Families or Groups.  Refer to p. 91-94 and p. 100-103.  The rows are called Periods and elements are arranged by their valence electrons, the electrons that are gained, lost or shared to create compounds.

Find the element chlorine on the Periodic Table of Elements.  Give all possible information.  Draw one atom of this element.

Using clues from the video of Discover the Elements, students tried to identify 20 to 30 of the most common elements.
