Presentation transcript:

Can you Find the pattern? Procedure Get a set of (10)element cards. Organize the cards by increasing mass, and start placing them into the 4x4 grid. Place each card based on its properties, and leave gaps when necessary

Analysis Make a table listing the placement of each element. Describe the period (across) and group (down) trends for the color in your new table. Describe the period and group trends for the mass in your new table. Explain your placement of any elements that do not fit the trends.

Analysis Describe the period (across) and group (down) trends for the color in your new table. Each group has its own color going across a period. ROYGBIV Going down a group, color gets lighter. Describe the period and group trends for the mass in your new table. The masses increase going across the period and down the group.

Predict the placement of a newly found element, Ph, that is a fuchsia gas. What would be an expected range for the mass of Ph? Predict the properties for the elements that would fill the last remaining gaps in the second and third rows of the table. Would there be any other possible arrangements of these “elements”? How did your table compare to other students’? Explain.

??? ??? ???

? ??? Ph 98.7 -106.9 g Gas Fuchsia 69.3 -83.4 g liquid Orange/Yellow Brittle Solid Green/light-Green Ph 98.7 -106.9 g Gas Fuchsia

Predict the placement of a newly found element, Ph, that is a fuchsia gas. What would be an expected range for the mass of Ph? Ph would be in group I (w/ Xn and Bp) with an estimated mass between 98.7 -106.9 g. Predict the properties for the element that would fill the last remaining gap in the table. It would be between Rx and Ax. It would be green to light green brittle solid with a mass between 106.9 -108.7 g.

Go back to your lab stations (groups of 4) & Now, try it again! Go back to your lab stations (groups of 4) & Organize your “Periodic Whos” On one sheet for your group, note the following trends: Arms Fingers Tummy Tattoos Hair Happiness Size Predict the missing “Who” –DRAW IT.
