Atom Project

Atom Project You’ve got your element, you know it

has value, now convince us…...  Sell us on this element through an

advertisement using PowerPoint….. 

Include…

Name of element (with Pronunciation guide)

Picture of the element Symbol Date it was discovered Atomic mass Atomic number Number of protons Number of neutrons Number of electrons Type of element

State of matter at room temperature

Discoverer Country of discovery Boiling point, Melting

point Isotopes, how many &

range of their masses Family and Period on the

periodic table Names of family members Uses, common compounds,

interesting facts) Cost = $____ per __ (ex $3.20 per gram)

Presentations will be on 10/22 and 10/23.

ChemCatalyst

Where did Mendeleyev place copper, Cu, on the periodic table he created? (Note: The atomic weight of copper is 63.)

Where would you put copper, Cu, on your periodic table? Explain your thinking.

The Big Question

How can you predict properties of elements using a periodic table?

You will be able to:

Interpret some of the information given in the periodic table.

Notes

The elements in the middle of the table are referred to as the transition elements, or the transition metals.

Activity

Purpose: This lesson will help to identify many of the patterns that are contained in the periodic table of the elements.

Making Sense

The elements copper and gold are both relatively unreactive. It is easy to bend and shape both metals. Both are used to make coins and jewelry. Is the similarity in their properties consistent with their locations on the periodic table? Explain why or why not.

Check-In

Use the cards for Cu, copper, and Au, gold, to describe all you can about the element silver, Ag.

Wrap-Up

Elements in each column of the periodic table have similar properties.

We can predict the characteristics of a missing element based on the qualities of the elements found adjacent to it in a periodic table.
