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.
In general, electronegativities of the elements in the same Period increases as you go from left to right across the period. As the nuclear charge increases and the atomic radius decreases across a period, the power of the atom's nucleus to attract electrons to itself increases.ey Concepts. 1  In 1932 Linus Pauling defined electronegativity as the power of an atom in a molecule to attract electrons to itself. 2  Pauling devised a numerical electronegativity scale, based on bond energies. 3  In general, electronegativities decrease down a Group of the Periodic Table.
