Elements and the Periodic Table

Activity One [|Chemical elements] are the fundamental building blocks for all matter in the universe. **Elements** cannot be reduced to simpler substances by ordinary means. All the atoms in an element are exactly alike; for example, all the atoms in a sample of pure gold are gold atoms (Au).
 * Part 1.**

The elements in the [|periodic table] are arranged in a very orderly fashion. Into what two main categories are the elements arranged?


 * Part 2.** Your teacher will give you a worksheet for your first assignment. Visit the [|CHEMystery] site to answer the questions on your worksheet about the periodic table.


 * Part 3.** Explain the logic behind the [|grouping of the elements].
 * 1) What do the elements in any given period have in common?
 * 2) What do the elements in any given group (family) have in common?

**Activity Two**
 * Part I.** The behavior of an atom's [|electrons] has a lot to do with where that element is placed on the periodic table.
 * 1) What factors connect the elements in [|Group I] to each other?
 * 2) **Helium** and **Hydrogen** are not in the same group. What do they have in common?
 * 3) How many electrons are found in the first orbital (k)?
 * 4) How many electrons can the second orbital (l) hold?
 * 5) How many electrons can the third (m) orbital hold if we confine ourselves to the first 18 elements?
 * 6) What is the maximum number of electrons that any orbital can hold?
 * 7) What theory is used to predict the locations of electrons around the nucleus?


 * Part 2.** We will be studying only the [|first 18 elements] in the periodic table. In using this table, click on the element and you will be taken to another page that is all about the element you selected. To learn more, click on the different selections in the column on the right.

We need to know certain [|specific information] about each of these 18 elements. In fact, each day we will learn about at least one element.


 * Part 3.** You will create a [|"card"] for the first eighteen elements listing the following [|information:] **atomic number, name of the element, symbol, atomic mass, number of protons, electrons and neutrons, Bohr diagram and Lewis dot structure.** You will use this information to create your own periodic table.


 * Part 4.** Take this [|quick quiz] about the the first 18 elements on the periodic table. **This quiz is a 10-point grade,** so be sure you know where the first 18 elements are located, to which rows and families they belong and how many valence electrons they have. Write the questions and the answers. Indicate which ones you missed and turn it in to the teacher.

You will be given a worksheet to follow along with a PowerPoint presentation on the **Periodic Table Basics.**
 * Part 5.**

**Activity Three**  **Project**
 * Your project will be to Adopt An Element. [|Directions] are given on this site. You will be assigned an element from the periodic table (there are many interesting ones) which you will use to create an advertising flyer. The above website also gives you a rubric to help in the development of your project.**

**Activity Four**  **Wrapping It Up**
 * Part 1.** Just for fun......This periodic table is beautiful and unusual and is interactive. Just click on the various [|elements] to find out what they are.

Once more just for fun: The [|periodic table] like you've never seen it before: animated and set to music.
 * Part 2.**
 * Ready for a quiz?** [|Let's see what you know.]

Also just for fun......[|Funbrain] has two games (one easy and one difficult) that you can play to further your knowledge of the periodic table. Also check out ths website for [|more games]on the periodic table. In the "Shared Activities" box that comes up, type in the words, periodic table. Then select the game you want to play.
 * Part 3.**

[|Here] is a good review page for the periodic table of the elements. There are a dozen student-made quizzes at the end of the page. Be sure you take advantage of these. They are interactive, so you can easily see how well you did.

[|This quiz] will be taken up for a grade, so do your best! **Activity Five**  **Test** **Test Wednesday, April 7, 2010.** BE SURE YOU CAN WRITE THE FIRST 18 ELEMENTS FROM MEMORY AND THAT YOU KNOW THEIR ATOMIC NUMBERS AND THE CORRECT SPELLING OF THE NAMES. YOU MUST BE ABLE TO ARRANGE THE ELEMENTS IN THE ORDER IN WHICH THEY OCCUR. YOU MUST ALSO KNOW THE NAMES OF THE GROUPS INTO WHICH THE ELEMENTS ARE SEPARATED, SUCH AS THE NOBLE GASES, THE ALKALI METALS AND THE HALOGENS. **In addition, you must know how to construct a Bohr model and a Lewis structure, if given the atomic number of an element**. GOOD LUCK!!!
 * Part 4.**

SPI 0807.9.9 Use the periodic table to determine the properties of an element. **Extra Credit Opportunity**
 * Complete this [|webquest] alone or with a partner. At the end of the webquest, you will present to the class a commercial about the element you chose. You may enact the commercial (as a skit) or videotape it and present to the class using the projector.**
 * Due Monday, April 12, 2010.**
