  1. Bonding Notes

  2. • Used to stabilize an atom = Atoms want to have a full outermost electron shell / energy level. • Turning atoms into Happy atoms

  3. • Atoms are CHEMICALLY bonded. *(This is the definition of a Compound) = Is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms *** Properties of the new substance (the compound) are different from the original elements.

  4. • Some examples: Sodium Soft, silvery white metal. Reacts violently with water. Chlorine Poisonous Greenish – Yellow gas NaCl = Sodium Chloride. Salt (Yummy on French Fries.)

  5. • Three main types of bonding: 1. Ionic bonds is transfering electrons. ** Occurs between a metal and a non metal

  6. Covalent bonds is the sharing of electrons. ** Occurs between two non metals

  7. 3. Metallic – Have free electrons from outer shells ** Occurs between two metals • Metal atoms form positve ions and act like buoys (floaty pool toys) and lifeguards for the negative electrons to swim around / be attracted to.

  8. Ions: What makes an atom an ion? Having a different number of protons and electrons • Can be positive or negative • Results from atoms gaining or losing electrons. * Negative ions have gained an extra e- (now they’re extra negative and have more e- than p+) * Positive ions have lost an e- (now they’re a less negative = positive and they have more p+ than e-)
