C. a reflected sound wave is absorbed by the medium, a diffracted sound wave changes direction as it passes through an opening Several examples are found in Table 3.3.1. In a true covalent bond, the electronegativity values are the same (e.g., H 2, O 3), although in practice the electronegativity values just need to be close.If the electron is shared equally between the atoms forming a covalent bond, then the bond is said to be nonpolar.. Usually, an electron is more attracted to one . in the bottom half paragraph one, it says: No. In Lewis terms a covalent bond is a shared electron pair. Because theyre polarized, two adjacent H2O (water) molecules can form a linkage known as a hydrogen bond, where the (electropositive) hydrogen atom of one H2O molecule is electrostatically attracted to the (electronegative) oxygen atom of an adjacent water molecule. As a result, each molecule has a definite, fairly rigid structure, or spatial distribution of its atoms. Therefore, both compounds most likely.
