Guy, Professor Terry and Sodium welcome you to BOOK 4 of the Happy Atom Story series. This book drops you into the lives of the Chemical families in Periodic Table Land. The Polyatomic Ions become Superhero Counselors who set up Clubhouses on each street in the land to help the elements solve their day to day problems. These Polyatomic Ions soon learn to form compounds and become happy just like the elements who became Happy Atoms. The cheerleaders from each of the Chemical families lead you in a chant that will help you forever remember the formulas and charges for all the Polyatomic Ions. Professor Terry uses her chemical journal to teach Guy how to write and balance chemical equations for each type of chemical reaction: Synthesis, Decomposition, Single Displacement and Double Displacement Reactions. The lesson on Balancing Equations takes place in Guy's mountain cabin where the little elements appear with tiny seesaws to allow Guy to see the difference between Balanced and Unbalanced equations. The big finale is a Labor Day parade and celebration where all the characters who featured in Guy's basic chemistry education, parade in front of the stage where Guy is honored for his achievements in learning Chemistry. The grand firework display by the lake is put on by Magnesium, Strontium, Copper and all the little elements who cause flames to be colorful. The story ends as it began with Guy enjoying the night sky and Wish Star dropping by to say goodbye. As Guy returns to the city to begin the school year, he brings lasting memories of his adventures in the fantasy world of Periodic Table Land. He learned basic Chemistry and so will YOU!
