  • Coulombs Law says

    when the radius is smaller the bonds are stronger

  • Ionic metals

    Transfer electrons

    Metals and non-metals

  • Molecular Covalent

    Share electrons

    non-metal elements

  • Metallic

    Strong

    in a sea of electrons

  • Extended Covalent

    Non-metal elements

    Lattice like structure of MANY MOLECULES

  • Why is MgBr2 harder than KF?

    MgBr2 has a total chare of 2 while KF has a total charge of 1. Compared to Mg K is lower on the periodic table and has an extra shell making it bigger. Based on coulombs law when the radius is smaller the bonds are stronger. MgBr2 have the strongest bond since it has a smaller radius in total.

  • Polar

    Electrons being pulled to one side more making that side delta (slightly) negative, and the other delta positive

  • Non-polar

    Share electrons

  • Intermolecular forces

    Interactions between molecules:

    Repulsion, attractions

    Ion Dipole

    Dipole-Dipole

    Hydrogen Bonding

    London Dispersion

  • Intermolecular forces are

    weak because small or partial charges are interacting over large distances.

    Exist between molecules

  • Intramolecular forces are

    strong due to large electrostatic interactions over short distances

  • Electron geometry

    Lone pairs count as a bond

    Lone pairs count as a bond

  • Molecular geometry

    Lone pairs are not counted but they help with form new shape

    Lone pairs are not counted but they help with form new shape

  • What is the Lewis Dot structure to

    Al2O3

    O Double bond Al Bond O Bond Al Double bond O (Add lone Pairs to O)

  • Calculate the frequency of light with a wavelength of 756nm

    use frequency formula

    1. Convert 756 nm to meters

    2. Plug into formula

    3. Your answer should be 3.96 x 10^15 Hz

  • A photon of light has an energy 1.23 x 10^-19 J. Determine the wavelength of the light wave:

    You are given E

    Use wavelength = hc/E

    You should have gotten

    1.65 x 10^-7
