worthy-an important, honorable person (word is often used humorously); he told his story to some conservative worthies; local worthies rarely challenged the chief constable. important person, influential person, personage-a person whose actions and opinions strongly influence the course of events.
Electronegativity Difference and Bond Character Covalent bond - a shared pair of electrons between two atoms Electronegativity - the ability of an atom to attract electrons in a covalent bond. Electronegativity Difference, E, E = E1-E2, For example, each HââO bond in H2O has: E = EO - EH E = 3.44 - 2.10 E = 1.44. As the electronegativity difference grows from 0.00 to >3.00, the sharing of electrons becomes more skewed. First one atom becomes partially negative, -, while the other becomes partially positive, +, and the bond is polarized, a polar covalent bond.
Electronegativity cannot be directly measured and must be calculated from other atomic or molecular properties. Several methods of calculation have been proposed and, although there may be small differences in the numerical values of the electronegativity, all methods show the same periodic trends between elements.n general, electronegativity increases on passing from left to right along a period, and decreases on descending a group. Hence, fluorine is undoubtedly the most electronegative of the elements while caesium is the least electronegative, at least of those elements for which substantial data are available.
