=Group Members: Samantha,Marlene, Keiysha, Chris, and Abi= =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?= > Some elements have some properties of metals, but not all properties of metals, these are called metalloids. Other elements have none of the properties of metals, these elements are called nonmetals. > Nonmetals are not good conductors or electricity. Most are brittle and dull in appearance. They are the far upper right side, above the zigzag. They are divided into two groups called halogens and noble gases. > Group 17 are the halogens. They are in the column labeled Group VII. Halogens are highly reactive. > Group 18 are the noble gases. They are in the column labeled Group VIIl. Noble gases are not reactive. > Hydrogen is a special element. It has properties of metals, but is a gas at room temperature. Hydrogen is labeled a nonmetal. > How to read the periodic table." //http://www.ehow.com/how_4716922_read-periodic-table-elements.html//. Web. 23 Feb 2010. .
 * 1) What is an element? A pure substance that cannot be broken down into other substances by chemical or physical means. //Prentice Hall science Explorer//. Boston, Massachusetts: Pearson Prentice Hall, 2005. 887. Print.
 * 2) What are elements made of? Elements are made up of atoms //Prentice Hall science Explorer//. Boston, Massachusetts: Pearson Prentice Hall, 2005. 887. Print.
 * 3) How are elements different from each other? The difference between one element and another stems from the number of protons and electrons in each atom. Each element has its own unique number of protons and electrons per atom eg Hydrogen atoms have 1 proton and 1 electron, Helium 2, Lithium 3 and so on. . //Prentice Hall science Explorer//. Boston, Massachusetts: Pearson Prentice Hall, 2005. 887. Print.
 * 4) How many different elements are there? 117. //Prentice Hall science Explorer//. Boston, Massachusetts: Pearson Prentice Hall, 2005. 887. Print.
 * 5) In terms of chemistry--what is a property? Physical change and Chemical change. Physical change can be any changes for example you can cause a physical change when you squash a marshmallow and when you do chemical change you can burn gasoline in a car's engine from //Prentice Hall science Explorer//. Boston, Massachusetts: Pearson Prentice Hall, 2005. 887. Print.
 * 6) How are elements on the periodic table grouped? Why?they are arranged by atomic numbers.. //Prentice Hall science Explorer//. Boston, Massachusetts: Pearson Prentice Hall, 2005. 887. Print.
 * 7) What are the vertical columns and the horizontal rows called on the periodic table? What are their significance? a group or a family. becuase the pattern of properties of elements repeats in each row. //Prentice Hall science Explorer//. Boston, Massachusetts: Pearson Prentice Hall, 2005. 887. Print.
 * 8) What are the features of the periodic table? (How do you read it?) Each element has its own square. The square on most tables give three major pieces of information. The first is the element symbol. This is the letter or letters in the middle of the square. The atomic number is the next piece of information. As mentioned earlier this number signifies the number of protons in the element, the number of protons is equal to the number of electrons. The third important piece of information is the atomic mass of the element, on earth the atomic mass is the same as the atomic weight. The elements are classified by properties. The properties define them as metals, nonmetals and metalloids. The metals are on the left side of the zigzag line on the table, while nonmetals and metalloids are on the right side of the zigzag. The elements in Group 1 are the alkali metals. They are the first column of the periodic table, labels Group 1A. The alkali metals are metals that form salts and other compounds. The alkali metals are all highly reactive.Group 2 contains the alkaline earth metals. They are in the second column of the periodic table, labeled Group llA. The alkaline earth metals form compounds.The next ten columns are groups 3 thru 12. These are the transition metals. These metals are in the columns labeled lB thru VlllB. The transition metals are hard metals such as gold. They have high melting points. They are very good electrical conductors. They are also malleable. Most of the metals on the table fall in these groups. These groups are broken up into smaller groups.Groups 13 thru 15 contain some metals, nonmetals and metalloids. These are mixed because the elements gradually transition from metal to nonmetal. These elements share some common properties. The metals in these particular groups are called basic metals.

=Mastery Assessment= //Deadline: 3/2/2010// Science Rocks, Inc. has hired you for a marketing assignment. 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.media type="file" key="periodictableinfomercial.3gp"
