You can use the periodic table to find the number of protons, neutrons and electrons that the atoms of an element have. All atoms of a particular element have the same number of protons and electrons, but the atoms may differ in the number of neutrons they have.  We will be using the periodic table in this activity to find out information about different elements on the periodic table. 

We are going to use the periodic table in today’s activity.  You will be using the table to tell me important information about an  element such as the number of electrons, protons and neutrons, the mass number, and the atomic number. 

Let’s look at the periodic table now.  To find out more information about an element, click on its symbol.  The trick is, you need to know the symbol for the element!  Hope you have been studying!  Right now, click on three different elements of your choice and write down this information about each element:

Name of element

Chemical symbol

Number of protons

Number of electrons

Atomic number

Atomic Weight

Here is an example of how you can find this information:

On the chart -   8 = the atomic number

                           O = the element symbol

                        Oxygen = the name of the element

                        15.9994 = the atomic weight/mass

      *** Remember***  Protons = Electrons = atomic number

When you are finished with this part of the assignment, I want you to pick your favorite element.  It could be the element you chose for your research paper or another element you would like to learn about.  Then I want you to complete the activity called “If I Were a ____________”.   You may need to go back and use the link to the periodic table to gather your information.
