Presentation Transcript

  1. DO NOW: • Identify the number of valence electrons in the following atoms: • Oxygen • Nitrogen • Carbon • Calcium

  2. CHEMICAL BONDING Objective: 1) To identify and diagram ionic and covalent bonds

  3. Physically Form mixtures Ex. Air Chemically Form compounds Ex. Water Elements can be combined in different ways:

  4. Compounds • Elements are combined in definite proportions • Represented by formulas • Show the kind and number of each atom • C6H12O6 • 6 carbon atoms • 12 hydrogen atoms • 6 oxygen atoms

  5. Atoms form bonds based on their outermost electrons • Valence electrons determine reactivity • 2-8-8 rule • Atoms whose valence shells are complete are stable/non-reactive

  6. Types of Bonds: • Ionic • Covalent • Hydrogen

  7. Ionic Bonding • Combines metal and non-metal • Electrons are transferred from one atom to another • Result in charge atoms called ions • Attraction between + and – keeps bond

  8. Ionic Bonding • Example: Na + Cl  Na+ Cl-

  9. One atom gives up an electron, one takes on an electron Sodium has 1 electron in its valence, chlorine has 7 electrons in its valence Sodium + Chlorine

  11. Covalent Bonds • Form between 2 non-metals • Electrons are shared • http://www.visionlearning.com/library/flash_viewer.php?oid=1348&mid=55
