1. Covalent Bonding with Bingo Chips Group#: ____ Period #: ___ Group Members: _________________________________________________________________________ ________________________________________________________________________________________ Instructions: • Work together to create these molecules: NH3, Cl2, H2O, and CO. • Find the atoms on the periodic table and determine the correct # of Protons, Neutrons, Electrons, and Valence Electrons. Write these numbers on this handout as well as on your atom whiteboards. • Place your valence electrons around the center of the atom. • Connect your atom to another atom by “sharing” the electrons. • Draw the molecules on this sheet using the following colors to indicate electrons: red, blue, green, and purple. • Put a box around all covalent bonds made. Jobs: [Note: you ALL must be responsible for at least one atom during the building process. Fail to work as a team will result in a loss of points] Materials Manager & Spokesperson: Calculations Expert: Artist: Writer: NH3 Cl2 P+: N: e-: Valence: Atomic #: ____ Symbol: ____ Mass #: ____ P+: N: e-: Valence: Atomic #: ____ Symbol: ____ Mass #: ____ P+: N: e-: Valence: Atomic #: ____ Symbol: ____ Mass #: ____

2. H2O CO • Write a reflection (5 – 8 sentences) to answer the 2 questions below. Since each student should participate, assign one color to each team member. Underline what each person thinks in their color. • Red: Blue: Green: Purple: • What did you learn about covalent bonds? • How was this different than when we made ionic bonds (with beads)?
