Name: Date Period Chemistry Scavenger Hunt Visit the Chemistry Links page at the Kid Zone to find these sites! CHEMystery Use this link: http://sciencespot.net/Pages/kidzone.html Go to “Matter Interactive” on then click on “Matter”. Matter is anything occupying _ and having ; it is the material of the . 1. There are three main phases of matter: , , and a fourth phase, , but it exists at very high temperatures. . There is also Science Is Fun Go to the “ChemTime Clock” and answer the questions below. http://www.scifun.org/ChemTime/ChemTime.html 1. All materials, whether solid, liquid or gas, are made of . Atoms are the smallest of . Scientists have found over different kinds of atoms. The many different materials we encounter are made from of these atoms. A material in which all atoms are the same kind is called an . Therefore, there are over different elements. Each element has been assigned a number, called its . 2. Search for information about each element on the Chem Time Clock. Use the chemical symbol to identify each element. Lightest atom First discovered in the sun Lightest metal Beryl, emeralds, and aquamarine Found in borax Atomic number of 11 Atomic number of 7 Diamond and graphite Major component of air 2nd most abundant element on Earth Used in making toothpaste Atomic number of 3 An element in table salt Glows red-orange with electricity Atomic number of 12 Name from Greek word for sun Used in “mag” wheels Most common atom in universe Atomic number of 9 Found in buckyballs Used in laundry detergents Atomic number of 2 Chem4Kids go to http://www.chem4kids.com/files/atom_intro.html Use the “overview”, “structure”, and “orbitals” areas in the right margin to find the answers to these questions. 1. Who developed the idea of electron shells, also called orbital shells? 2. What are the three “pieces” to an atom? Go to “bonding” in the right margin to find the answers to these questions. 1. What is meant by an atom being “happy” ? 2. How many electrons can fit in the 1st shell? The 2nd? Go to “Compound Names” on the right to find the answers to these questions. 1. How many chlorine atoms would be in a compound with the name: a. dichloride? b. tetrachloride? c. decachloride? 2. What do you get when you add the following atoms together? a. one carbon and one oxygen? b. one carbon and two oxygen? c. one carbon and four chlorine?
