Humor: On the Fun Side

  1. Capitalism reigns in the atomic world. The unequal sharing of electrons is the central concept of bonding. One of history's most sage remarks concerning sharing was uttered by Winston A. Churchill, Prime Minister of England during World War II. Churchill's quotation was once used in a beer advertisement as follows:

    What did Churchill actually say? (Yes, the unequal sharing of wealth!) This was, indeed, a very wise remark on Churchill's part. Some people do have more Budweiser, wealth, luck, and wisdom than do other people. Some atoms, on the other hand, are more electron-wealthy than others-they are said to be more electronegative! Fluorine is the most wealthy, the most capitalistic of all atoms. Electrons are not shared equally between atoms unless those atoms are the same, so unequal sharing is the normal situation. Capitalism reigns supreme in the atomic world!

  2. Elements 4 and 18 (from the alkaline earth and noble gas families) form a 1:1 compound that is polar. What is the compound's color and formula? Answer: BeAr which, given that it's polar and has a white color.

  3. Question: What is the name of 007's Eskimo cousin? Answer: Polar Bond.

  4. Limericks:
  5. Rhyme:
    Chemistry is full of rules
    Atoms, moles, and molecules.
    Some of which might fit together,
    Maybe now, and likely never.
    (CHEM 13 NEWS, January 1972, p. 380)

  6. Message on a T-shirt: Together we could make beautiful molecules.

  7. The adjacent Lewis-dot diagram for Br 2 was one of several similar variants submitted on a recent test by students who shall remain anonymous. (CHEM 13 NEWS, December 1991, p. 2)


  8. CHEMTOON:

    We seem to be poles apart. (CHEM 13 NEWS, September 1983, p. 15)


  9. ON HYBRIDS
    Beryllium gave many a plea
    'Cause it's valence electrons weren't free
    And it couldn't combine
    till a thought came to mind
    And it went and invented sp!
    Boron's not satisfied yet
    Its demands really cannot be met
    Though it tries hard to be
    Like He or Ne
    sp 2 is the best it can get.
    Carbon's like one seen before
    His shells couldn't hold any more
    Till his friends lent a hand
    showed him how to expand
    And sp 3 lets him join up with four!
