=Group Members: = **Shaquanda Johnathan Quante Brie**

=Organization is key! =  Do you lose stuff in your bedroom? Have you spent countless hours looking for that lost sock or that missing piece of Ms. Johnson's homework? If so, then you need ORGANIZATION! Science is all about organization. Your Mastery Assessment is to create an an infomercial with the purpose of selling the periodic table to a group of very unorganized scientists.

=What should you know? =
 * 1) What is an element? **Quante : A substance that can NOT be broken down into other substances by chemicals or physical means **
 * 2) What are elements made of? **Quante : One kind of atom **
 * 3) How are elements different from each other? **Brie : By the different atoms that create it. **
 * 4) How many different elements are there? **Brie : more then 100 different kinds **
 * 5) In terms of chemistry--what is a property? **Shaquanda :A Characteristic of a sample of atter that is fixed by its state. **
 * 6) How are elements on the periodic table grouped? Why? **Johnathan : By similar resemblance. So it would get them mixed up. **
 * 7) What are the vertical columns and the horizontal rows called on the periodic table? What are their significance? **Shaquanda :Its called groups of families often the elements that are found in the same group as each other have similar chemistry and reactivity. The periodic table help people deal with Chemistry. **
 * 8) What are the features of the periodic table? (How do you read it?) **Johnathan : By the atomic number, chemical symbols, element name, and atomic mass. **

=**Additional Questions** =  **Resources: North Carolina Grade 8: Prentice Hall Science Explorer Book**
 * 1) <span style="font-family: Impact,Charcoal,sans-serif;">How many different groups are on the periodic table? **18 different groups**
 * 2) <span style="font-family: Impact,Charcoal,sans-serif;">Are there any elements that are NOT in a specific group? If so, which elements? **Hydrogen**
 * 3) <span style="font-family: Impact,Charcoal,sans-serif;"><span style="font-family: Impact,Charcoal,sans-serif;">**Why where some transition metals placed at the bottom of the table and what are they called?** **Lanthanides and Actinides**
 * 4) <span style="font-family: Impact,Charcoal,sans-serif;">What is the difference between the two? **Lanthanides are shiny and reactive, while Actinides are all radioactive, thus unstable.**

You and your team have been tasked with creating an infomercial with the purpose of selling the periodic table to a group of unorganized scientists. They see nothing wrong with the way they keep their elements "organized" so you must point out every feature of the periodic table to prove to them they //need// this tool.
