Create a Table

• Create a Table card deck

1. Work in groups of four with one set of cards.

2. Find Be, Mg, Ca, and Sr in the deck of cards, and arrange them in a column as shown to the right. These cards are all yellow. Look for similarities and differences in these cards. Find at least one pattern or trend, and describe it to your group.

2. What patterns appear in your arrangement? List at least four.

3. Where did you put H and He? What was your reasoning for their placement?

4. Did you notice any cards that didn’t quite fit or that seemed out of order? Explain.

   2. Which card seems most accurate to you? What is your reasoning?

   3. What would you add to the three empty corners to complete the card?
