The Chemistry of Life
Rub a balloon to create a static charge. Gently run water out of the faucet. Hold the balloon next to the stream of water without touching it! (dry with paper towel if needed) Make the water dance Sit with your table and discuss how that happens. Jot down your ideas…
Atoms join with other atoms to form stable substances. Atoms want to have a full valence orbital to become stable. It involves just the v valence electrons.
Individually you will be responsible for reading about Ionic Bonds, Covalent Bonds, and Hydrogen Bonds in your textbook (pgs. 29 & 30) Complete the “Bonding” guided notes. Once you have completed the notes, take turns going around your table confirming the information.
Occurs between a Nonmetal & Nonmetal Sharing of electrons Form Molecules Ex: CO 2, H 2 O, O 2, CH 4
Occurs between a Metal & Nonmetal Gain or Lose Electrons Metal gives e- to nonmetal Ex: NaCl ◦ Chlorine takes e- ◦ Sodium gives e- Ion: Atoms electrically charged from gaining or losing electrons.
