  1. dfadsk;lf
  2. Electronegativity-
    The ability of an atom to attractelectrons to itself in a chemical bond (polar bonds)
  3. The steps in converting a molecular formula into a Lewis structure.
    • 1) (molecular formula) Place atom with lowest EN in center
    • 2) (atom placement) Add A-group numbers INCLUDING CHARGE (+ or -)
    • 3) (sum of valence e) Draw single bonds. Subtract 2e- for each bond.
    • 4) (remaining valence 2) Give each atom 8e- (2e- for H)
  4. What will never form double bonds
    fluorine
  5. resonance structure.
    have the same relative atom placement but a difference in the locations of bonding and nonbonding electron pairs.
  6. A more negative formal charge should exist on an atom with a
    larger Electronegativity value
  7. It must follow octet if
    It doesan't have a d orbital, or there any other reasons to or not to follow it?
  8. Sharing electrons pulls them together, so ---------- are the longest
    single bonds. Bond length and strenth are inversly related.
  9. Which bonds are the hardest to break?
    Triple bonds
  10. Negative heat of reaction means it was
    an exothermic reaction
  11. Electronegativity-
    The ability of an atom to attractelectrons to itself in a chemical bond (polar bonds)
  12. 0
    <0.4
    0.4-1.7
    >1.7 (or 2 in mastering chem)
    • nonpolar covalent
    • mostly covalent
    • polar covalent
    • mostly ionic
  13. What is ionic character?
