 Atom: ◦ The smallest particle of an element  Molecule: ◦ A particle made up of two or more atoms bonded together  Chemical Bond: ◦ The force that holds atoms together -the “glue” that makes the atoms “stick” to each other

 Chemical Formula- ?  A combination of symbols that represent the numbers in a compound  Subscript- ? ◦ The (small) number in a chemical formula that tells the number of atoms in a molecule or the ratio of elements in a compound  Ex: H 2 0

 Partner up with another group or work with your partner and use your gum drop atoms to create a molecule.  Your gum drops now represent elements… Which ones? You decide! Make each color a different element.  Try to create a Water molecule first, draw what you see, label what each is then write the molecular structure. Next try the ones on the data table or try to make your own.  You may use your periodic table for help.
