Chem Bonding

  1. An Ionic Bond
    • is the electrostatic attraction
    • experienced between the electrical charges of a cation and an anion.















    • They are formed when one or more
    • electrons are transferred from one atom to another. The driving force
    • for this transfer is usually the formation of a noble gas
    • configuration.
  2. Oxidized
    means losing an electron
  3. Reduced
    means gaining an electron.
  4. onic compounds are typically
    • solids with lattice-type structures.
    • (kup)
  5. Ionic compounds have high melting
    points due to
    • strong electrostatic forces of
    • attraction between the ions in their lattice structures.(is directly
    • proportional to interacting charges, so mg 2 and o 2 have a higher
    • melting point than na 1 cl 1)
  6. Volatility is the
    • tendency for a substance to vaporize.
    • It's low for ionic compounds.
  7. In their solid form, electrons are
    fixed
    • so they do not conduct electricity.
    • However, in their molten or solution state, the electrons are free to
    • move and conduct electricity
  8. A covalent bond is formed by
    • the electrostatic attraction between a
    • shared pair of electrons and the positively charged nuclei. (a region
    • of relatively high electron density between nuclei that arises at
    • least partly from shared electrons)
  9. Bond length decreases
    • and bond strength increases as the
    • number of shared electrons increases.
  10. When you write Lewis structures of
    cations or anions
    • you should always include square
    • brackets with their charge and their shit.
  11. Increasing molecular size will
    increase melting point and stuf

    Seasaw



    • 90 degrees and 118 degrees between the
    • two bonded in the middle


    • it's like bend but has two sticking out
    • and the inbetween is like 118 degrees
  25. 5 Regions of Electron Density 3 bonding
    2 lone
    T shaped



    90 degrees
  26. 5 Regions of Electron Density 2 bonding
    3 lone
    linear



    180 degrees
  27. 6 Regions of Electron Density 6 bonding
    0 lone
    octahedral


    90 degrees
  28. 6 Regions of Electron Density 5 bonding
    1 lone
    • it loses one of the things sticking out
    • from down under and becomes a square pyramidal



    with 90 degrees
  29. 6 Regions of Electron Density 4 bonding
    2 lone
    • it loses both things sticking out from
    • down and up and turns into


    square planar



    with about 90 degrees
