Developing the Periodic Table

Introduction and History:For a long, long time, scientists have known that certain elements behaved similar

These elements formed similar compounds, formed ions with similar charges, and

had similar physical properties. Around 1870, two scientists, Meyer and Mendeleev

came up with a way to organize elements. Surprisingly, they did not work together or

collaborate. They individually worked and created their own periodic tables.

The periodic table that we use today is based on the ones they have made. In this

activity, we will create our own table in a way similar to their work.

Purpose:

You will learn how elements are grouped in the periodic table and face the

challenges of doing so.

Materials and apparatus:

Element cards & Your brain!

Procedure:

Work in groups of 2-4. Your teacher will give each group a set of element cards. Eacard will contain information about the element. You will need to arrange these cards in

a table similar to the periodic table. Obviously, these elements are fictitious and do not

exist. However, the frustration that you will face is very real.

PART 1 of 2 :

You will arrange 23 elements in a table that makes sense to you. Pay attention to

what compounds and charges the elements form.Also pay attention to their physica

properties. Think about how our modern day periodic table is arranged. By mass? By

charges of ions? By compounds formed?

Questions:

1. How many groups (columns) or families of elements are in your table?

2. How did you determine which elements belonged to what groups?

3. Is there a pattern in atomic mass going across the table? Is there a pattern going

from top to bottom?

4. Are there any exceptions? Did you choose to ignore them or accept them?

5. Are there any hopes or gaps in your arrangement? Can you predict the properties

the elements that should fill these gaps?

PART 2 of 2:

When you are done with the questions in part 1, ask your teacher for the elements

in part 2. Answer the following questions:

Questions:1. Compare your answers from Part 1 Question 5 to the element cards given to you. D

they match?

2. Try placing these elements in the periodic table. Which ones did you have trouble

fitting in the periodic table? Explain what caused the trouble.

3. The masses of Ri and Tf do not fit the pattern in our periodic table. In the modern

periodic table, tellurium and iodine do not fit the pattern either. How are elements

in the modern periodic table arranged?

4. Suppose that we discovered a new element Md. This new element Md has a mass o

55.0, forms +4 charge, and is a soft grey metal. Where would this element fit in ourversion of the periodic table?

5.

What compound would Md form with N from our periodic table?

Conclusion:

Write a short paragraph (5-8 sentences) on your experience arranging these

elements into a table. Comment on the problems you faced and how you managed to

overcome them.
