 Atoms are the smallest form of matter  Nucleus: ◦ Protons (positive) ◦ Neutrons (neutral) ◦ Protons & neutrons make up most of the atom’s mass  Energy.
Isotope: Same element (same number of protons) but with different number of neutrons. Same # of Protons Different amount of Neutrons We know these are.
Matter- anything that has mass and occupies space Atom- basic unit of matter Subatomic particles: Protons (+) –in nucleus, 1 amu Neutrons (0) –in nucleus,

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.
