Know more about coffee's origins and the Ethiopian drinking coffee ceremony. I got this funny idea of Google-searching for "the coffee addict's prayer". And here is a part of what I've found: "Caffeine is my shepherd; I shall not doze. It makes me wake in green pastures; it leads me beyond the sleeping masses."

The French statesman named Talleyrand made a quite witty description of his favorite type of coffee: "Black as the devil, hot as hell, pure as an angel, sweet ...

TRENDS IN ELECTRONEGATIVITY OF 3rd PERIOD

Electronegativity is a measure of the tendency of an atom to attract a shared pair of electrons towards itself. Elements Na Mg Al SI P S Cl Ar Electronegativity 0.93 1.13 1.81 2.02 2.19 2.58 3.16 - Note that EN of Ar is not included. Electronegativity is related to the tendency of an atom to attract the shared pair to attract the shared pair of electrons. Since Argon does not form covalent bonds, you obviously cannot assign it an electronegativity value. Moving from one elements to the next across the period, nuclear charge increases by 1 unit and one electron is added to the outer shell. As the positive charge on the nucleus rises, the atom has increasing electron attracting power and therefore an increasing electronegativity.
