5 Multiple choice questions

  1. when the electrons aren't shared equally
    unequal distribution of charges
    \electrons are closer to the atom with the greater electronegativity and produces a negative charge
  2. tbe ability of an atom to attract an electron.
    most electronegative: F, O, N
  3. weak bonds between molecules
    form when H+ is in a covalent bond, but is attracted to another molecule [usually with a high electronegativity] in another covalently bonded molecule
  4. the chemical bond that forms between two atoms when one or more electrons are transformed from one atom to anohter.
    happens when the electronegatives differ
    creates ions
  5. 1. Universal Solvent
    2. High Heat Capacity
    3. Ice
    4. Strong Cohesion/High Surface Tension
    5. Adhesion
