November 12, 2009

We had a quiz today over Section 2 of Chapter 6. Then we took a couple notes:

  • In a metal, the vacant orbitals in the atom's outer energy levels overlap.
  • This overlapping of orbitals allows the outer electrons of the atoms to roam freely through the entire metal.
  • The electrons are Delocalized, which means that they don't belong to any one atom, but move freely about the metal's network of empty atomic orbitals.
  • they form a sea of electrons around the metal atoms, which are packed together in a crystal lattice.
  • Metallic Bonding - results from attraction between metal atoms and the surrounding sea
Dr. B reminded us that we should be working on our outlines and reading along and ahead in the textbook.
Have a good night!

    http://en.wikipedia.org/wiki/Delocalized_electron

    This gives a little more info on delocalized electrons.
