There are three main phases of matter: _____________, ____________, and _____________. There is also a fourth phase, ______________, but it exists at very high temperatures. 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.
