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.
Best Answer: In general, the metals combine with nonmetals through ionic bonds. Nonmetals combine with other nonmetals by covalent bonds. A simple way to decide if a substance is covalent or ionic is to compare the electronegativities of the elements involved in the bonding.Electronegativity is a measure of the pull on shared electrons between to atoms. In NH3, the electronegativity of N is 3.04 and H is 2.20.If the difference in electronegativity is less than about 1.7, the bond is covalent. So NH3 is made of covalent bonds. But, the N has a stronger pull on the shared e-compared to the H, so the nitrogen is partially negative and the hydrogen is partially positive. simple way to decide if a substance is covalent or ionic is to compare the electronegativities of the elements involved in the bonding. Electronegativity is a measure of the pull on shared electrons between to atoms.
